#### Question 1:

Draw a rectangle of length 8 cm and width 6 cm. Divide it into three equal parts and complete the flag.

The top one – third of our flag is saffron (or orange). What is the colour of the middle one – third of the flag? Where will you draw the Ashoka chakra?

How much of the flag will you colour green?

#### Answer:

The colour of middle one-third of the flag is white. The Ashoka chakra is drawn at the centre of the flag. One-third of the flag is coloured green.

#### Question 2:

Now look at this flag. How much of it is black? ________ The green part of the flag can be written as ________ Is red less than one – third of the flag? Why?

#### Answer:

Total number of parts of the flag = 3 Now, we see that out of three equal parts, only one part of the flag is black. Thus,

13of the flag is black.

We can also see that out of three parts of the flag, only one part is green. Thus, green part of the flag is

13of the flag.

The red portion of the flag is less than

13of the flag, because a white emblem is also present in the red portion of the flag.

#### Question 3:

This is the flag of Myanmar, our neighbour. Is blue more than one-fourth of the flag or less? Guess how much of the flag is red. Is it more than

12? Is it more than three-fourths?

#### Answer:

The blue colour is present in less than one-fourth of the flag.

I think, red colour is present in more than three-fourth of the flag.

#### Question 2:

* Chocolate bar* • Manju had a chocolate. She gave one-fourth of it to Raji, one-third to Sugatha and one-sixth to Sheela. She ate the remaining part. How many pieces of chocolate did each get?

• What part of the chocolate did Manju eat?

#### Answer:

Total number of pieces in the chocolate bar = 12

Manju gives one-fourth of the chocolate to Raji. Number of pieces of chocolate given to Raji = 12 ÷ 4 = 3

Thus, Raji got 3 pieces of chocolate. Now, Manju gives one-third of the chocolate to Sugatha. Number of pieces of chocolate given to Sugatha = 12 ÷ 3 = 4

Thus, Sugatha got 4 pieces of chocolate. Now, Manju gives one-sixth of the chocolate to Sheela. Number of pieces of chocolate given to Sheela = 12 ÷ 6 = 2 Thus, Sheela got 2 pieces of chocolate. Total number of pieces of chocolate given to Raji, Sugatha and Sheela = 3 + 4 + 2 = 9 Total number of pieces of chocolate left in the bar = 12 − 9 = 3

As Manju ate the remaining part of the chocolate, she will get 3 pieces of chocolate. Part of the chocolate eaten by Manju =

#### Answer:

Total number of hats = 15 It is given that we have to colour

13of hats in red. Number of red coloured hats = 15 ÷ 3 = 5 = 5

It is given that we have to colour

35of the total hats in blue.

One-fifth of the total hats = 15 ÷ 5 = 3 Number of blue coloured hats = 3 × 3 = 9

Number of hats that are not coloured = 1 Thus, part of hats that are not coloured =

#### Question 1:

**Greedy Gatekeepers** Remember Birbal, the clever minister of King Akbar? (Math-Magic Class IV. page 14) Do you know how he became a minister? Birbal was then a young boy living in a village. He was very clever and could write poetry. He thought he would try his luck in the King’s court. So he took some of his poems and set off for the city. When he reached the outer gate of the palace, he was stopped by the gatekeeper. “Hey! Stop there! Where are you going?”, shouted the gatekeeper. “I am a poet. I want to see King Akbar and show my poems to him”, replied the poet. “Oh, you are a poet! The king is kind, he will surely give you a prize. I will let you in if you give me

110of your prize”.

Young Birbal agreed since he had no other way. When he went in, the gatekeeper calculated “If he gets 100 gold coins I will get _________ gold coins”. The poet came to a second gatekeeper. This gatekeeper also said, “I will let you in if you give me **two-fifth** of your prize”. The poet agreed. The gatekeeper happily calculated, “The poet will get at least 100 gold coins so I will get ___________ gold coins!” The poet reached the last gate. The gatekeeper said, “I will allow you to see the king only if you give me **half **of the prize that you get”. The poet had no other way. He agreed and went inside. The gatekeeper thought, “Today is a great day. If he gets 100 gold coins I will get __________ gold coins. But if he gets 1000 coins â€• wow! I will get ____________”. The king was very happy with the poems and said, “Your work is very good. You can ask anything as your prize”. “My Lord, I want 100 slaps”. “What! 100 slaps? ___________”. The king was shocked â€• • What happened after that? Complete the story. What part of the prize did the poet get?

#### Answer:

The first gatekeeper thought that the king would give 100 gold coins to Birbal as a prize. The first gatekeeper demanded

110 of the prize that he would get from the king. So, number of gold coins that would be received by first gatekeeper = 100 ÷ 10 = 10

The second gatekeeper demanded

25 of the prize that Birbal would receive from the king. One-fifth of 100 = 100 ÷ 5 = 20

So, number of gold coins that would be received by second gatekeeper = 20 × 2 = 40

The third gatekeeper demanded half of the prize that Birbal would receive from the king. So, number of gold coins that would be received by third gatekeeper = 100 ÷ 2 = 50

After listening to his poems, the king became happy. Then, Birbal requested the king to give him 100 slaps as a prize.

Hence, the third gatekeeper got 50 slaps, second gatekeeper got 40 slaps, and the first gatekeeper got 10 slaps. The poet got 0 slaps.

#### Question 1:

Ramu’s vegetable field has 9 equal parts. What vegetables does he grow?

(1) Which vegetable grows in the biggest part of his field? What part? (2) On what part of the field does he grow potatoes? (3) What part of the field is used to grow spinach? What part is used for brinjals? (4) Now you write some questions by looking at this picture.

#### Answer:

Ramu grows capsicum, brinjal, tomatoes, spinach and potatoes in his field.

1) Total number of parts of the vegetable field= 9 Ramu grows tomatoes in the biggest part of his field. Part of field used for growing tomatoes = 3 Part of field used for growing tomatoes =

39 =

13 Ramu grows tomatoes in one-third of the field.

2) Part of field used for growing potatoes = 2 Total number of parts of the vegetable field = 9 Part of the field used for growing potatoes =

29 So, Ramu grows potatoes in two-ninth part of the field.

3) Total number of parts of the vegetable field = 9 Number of parts used for growing spinach = 1 So, part of the field used for growing spinach =

19 Number of parts of field used for growing brinjals = 2 So, part of the field used for growing brinjals =

29 Thus, Ramu grows spinach and brinjals in one-ninth and two-ninth part of the field respectively.

4) (1) Which vegetables are grown in the least part of the field? (2) What is the part of the field used to grow raddish and tomatoes together? **Disclaimer:** The answer to part (4) of the question may vary from student to student. It is highly recommended that the students prepare the answer on their own. The answer provided here is for reference only.

#### Question 1:

Ramu wanted to give below vegetables to his friends. He gave Aboobacker one-fifth of these tomatoes and

13of the potatoes. Srija got

25of the tomatoes and

36of the potatoes. Nancy got the rest of these vegetables. Circle Aboobacker’s share in blue. Circle Srija’s share in yellow.

• How many potatoes and tomatoes did Nancy get?

#### Answer:

Total number of tomatoes = 20 Total number of potatoes = 18

Aboobacker got one-fifth of the tomatoes, and one-third of the potatoes.

Number of tomatoes with Aboobacker = 20 ÷ 5 = 4 Number of potatoes with Aboobacker = 18 ÷ 3 = 6

So, we will circle 4 tomatoes and 6 potatoes in blue to show Aboobacker’s share. Srija got two-fifth of the tomatoes and three-sixth of the potatoes. Number of tomatoes with Srija = 2 × 4 = 8 One-sixth of 18 = 3 Number of potatoes with Srija = 3 × 3 = 9

Thus, Ramu gave 4 tomatoes to Aboobacker and 8 tomatoes to Srija. So, he gave a total of 12 tomatoes to Aboobacker and Srija.

Now, Ramu gave 6 potatoes to Aboobacker and 9 potatoes to Srija. So, he gave a total of 15 potatoes to Aboobacker and Srija.

Number of tomatoes left = 20 − 12 = 8 Number of potatoes left = 18 − 15 = 3

Thus, Nancy got 8 tomatoes and 3 potatoes.

#### Question 1:

Ramesh bought a piece of halwa for his children Ammu and Anu. He divided it equally for them. • Each will get __________ part of halwa. “This piece is too big. We can’t eat it”, they said. So he divided the pieces into half again. Now how many pieces will Ammu get? ________ • What part of the halwa is it? _________ “Make it even smaller, Dad” they asked. So he again cut the halwa into smaller pieces. “Ok, thank you, Dad.” • Now how many pieces will each get? • What part of the halwa is each piece now? • If Ramesh had cut the halwa into 6 equal parts how many pieces would each have got? Look at your answers for questions 1 to 4 and write â€•

12= â€• = â€• = â€• = â€• = â€•

#### Answer:

• When Ramesh divides the piece of halwa in two parts,then each child will get half part of halwa. Each will get

12part of halwa.

• When each of the two pieces of halwa is divided into 2 equal parts, then there will be a total of 4 pieces of halwa. Now, each of the child gets 2 pieces of halwa.

Thus, Ammu will get 2 pieces of halwa.

Total number of pieces of halwa = 4 Number of pieces with Ammu = 2 Part of halwa that Ammu gets =

24=

12Thus, Ammu will get half part of the halwa.

• When each of the 4 pieces cut again into halves, then we have a total of 8 pieces of halwa. Now, each child will get 4 pieces of halwa.

• As one whole piece of halwa is now divided into 8 equal halves, each piece is

18part of the whole piece.

• When Ramesh divides the halwa into 6 equal parts, then each of the 2 child gets 3 pieces of halwa.

12 = 24 = 36 = 48 = 510 = 612

How many will make one rupee? Is 50 paise half of one rupee? How many will make one rupee?

25 paise is _________ part of one rupee 20 paise is _________ part of one rupee How many 10 paise will make one rupee? So 10 paise is ________ part of one rupee.

#### Answer:

We know that,

One rupee = 100 paise Number of 50 paise coins in one rupee = 100 ÷ 50 = 2

So, two 50 paise coin will make one rupee.

There are two 50 paise coin in one rupee. So, 50 paise is half of one rupee.

We know that, 100 paise = Re 1 Number of 25 paise in one rupee = 100 ÷ 25 = 4 So, four 25 paise coins will make 1 rupee.

We know that, four 25 paise coins will make 1 rupee. So,25 paise is __one-fourth__ part of one rupee.

Number of 20 paise coin in one rupee = 100 ÷ 20 = 5

There are five 20 paise coin in one rupee. So, 20 paise is __one-fifth__ part of one rupee.

Number of 10 paise coin in one rupee = 100 ÷ 10 = 10 Ten 10 paise coin will make one rupee.

So 10 paise is __one-tenth__ part of one rupee.

#### Question 1:

* An Old Woman’s Will* Once there lived an old woman. She lived with her three daughters. She was quite rich and had 19 camels. One day she fell ill. The daughters called the doctor. The doctor tried his best but could not save the woman. After her death, the daughters read what she had written in her will.

My eldest daughter will get12of my camels My second daughter will get
14of my camels My third daughter will get 15of my camels |

The daughters were really puzzled. “How can I get

12of the 19 camels?” asked the eldest daughter. “Half of 19 is nine and a half. But we can’t cut the camel!” The second daughter said. “That is right. But what will we do now?” asked the third daughter”. Just then they saw their aunt coming. The daughters told her their problem. “Show me the will. I have an idea. You take my camel. So you have 20 camels. Now can you divide them as your mother wanted?” the aunt said. “You want half of the camels, don’t you? Take 10 camels” she said to the eldest daughter. “Take your share”, the aunt told the second daughter. She took one-fourth of the camels and got _________ camels. “You can take one-fifth of the camels”, the aunt told the third daughter. She got ________ camels. The daughters were very happy and counted their camels 10+____+____=19. “The one remaining is mine”, said the aunt and took her camel away!

• How did this happen? Discuss.

#### Answer:

Total number of camels = 20 Number of camels given to first daughter = 20 ÷ 2 = 10 Thus, first daughter got 10 camels in her share.

Number of camels given to second daughter = 20 ÷ 4 = 5 Thus, second daughter got 5 camels in her share.

Number of camels given to third daughter = 20 ÷ 5 = 4 Thus, third daughter got 4 camels in her share.

10 + __5__ + __4__ = 19 When the daughters counted their camels, they found that there were in total 19 camels to be divided among them in total.

The division of 19 camels among 3 daughters in the given fractions was possible only when the aunt included her camel.

14of a day How many hours does Arun take for

Sleeping? hours

Studying? hours

Playing? hours What part of the day does he use for other activities?

#### Answer:

Total number of hours in 1 day = 24 Arun sleeps one-third of a day. Number of hours that Arun sleeps = 24

÷3 = 8

Thus, Arun sleeps for 8 hours in a day. Arun plays for one-eighth of a day. Number of hours Arun takes to play = 24

÷8 = 3 Arun studies one-fourth of a day. Number of hours Arun takes to study = 24

÷4 = 6

Total number of hours spent in studying, playing and sleeping = 6 + 3 + 8 = 17 Number of hours left for other activities = 24 − 17 = 7 So, part of the day used for other activities =

724Thus, Arun uses seven twenty-fourth of the day for other activities.

#### Answer:

We know that,

1 year = 12 months Quarter of an year = 3 months Number of quarters in 1 year = 12 ÷ 3 = 4

A school brings 1 magazine every quarter of the year. Number of magazines brought by school in 1 year = 1 × 4 = 4

As the magazines are printed at the end of each quarter of the year, March, June, September and December will be the months for printing.

So what part of a year do they sleep? A person 60 years old must have slept ________ years!!!

#### Answer:

Total number of hours in one day = 24 Number of hours people slept = 8 Part of the day people slept =

824 =

13It is one-third part of a day.

Number of days in one ordinary year = 365 Number of hours in one day = 24 Number of hours in 365 days = 365 × 24 = 8760

Number of hours that people slept in 1 day = 8 Number of hours that people slept in 365 days = 365 × 8 = 2920

The part of the year that people slept =

29208760 =

13So, people slept one-third of the year.

A man sleeps one-third part of an year. Number of years a man of 60 years slept = 60 ÷ 3 = 20

Thus, a man of 60 years must have slept 20 years.

212hours from this station. What time will she get off? (c) Shaji will take 5 hours to reach Ernakulam by this train. At what time will he reach there?

#### Answer:

a) The correct time for the arrival of the train is quarter to 7

=

634hrs

But, the train is late by half an hour.

So, expected time of the arrival of the train =

634 + 12 =

274 + 12 =

274 + 1 × 22 × 2 =

274 + 24 =

294 =

714 Thus, the expected time of the arrival of the train is quarter past 7.

b) Expected time of the arrival of the train =

714hrs

Nazia gets off at a station after

212hrs of boarding the train.

Time at which Nazia will get off =

714 + 212 =

294 + 52 =

294 + 5 × 22 × 2 =

294 + 104 =

29 + 104 =
