b) The green part of the flag can be written as.........

c) Is red less than one-third of the flag? Why?

Answer :

a) The flag is divided into three equal parts. Each part is one-third of the flag. Therefore, the one-third of the flag is black.

b) Since each part is one-third of the flag, the green part of the flag is one-third of the flag.

c) There is a white emblem in the red coloured portion. Therefore, the red colour is less than one-third of the fag.

Question 1 :

**A) Chocolate bar**

a) 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?

b) What part of the chocolate did Manju eat?

Answer :

a) The chocolate is divided into 12 equal pieces.

Step 1: Since Raji got one-fourth of the whole chocolate, multiply 1/4by 12 to find the share of Raji.

1/4 X 12 = 12/4 = 3

Therefore, Raji got 3 pieces of the chocolate.

Step 2: Since Sugandha got one-third of the whole chocolate, multiply 1/3 by 12 to find the share of Sugandha.

1/3 X 12 = 12/4 = 4

Therefore, Sugandha got 4 pieces of the chocolate.

Step 3: Since Sheela got one-sixth of the whole chocolate, multiply 1/6 by 12 to find the share of Sheela.

1/6 X 12 = 12/6 = 2

Therefore, Sheela got 2 pieces of the chocolate.

Step 4: Since Manju ate the remaining part, add the shares of each of her friends and then subtract the result from 12 to find the share of Manju.

4 + 3 + 2 = 9 12 – 9 = 3 Therefore, Manju got 3 pieces of the chocolate.

b) Since Manju got 3 pieces out of 12 pieces of the chocolate, divide 3 by 12 to find the portion of the whole chocolate that Manju ate.

3/12 = 1/4

Therefore, Manju got one-fourth of the chocolate.

Question 2 :

B) Colour the hats

a) Colour 1/3 of the hats red. Colour three-fifth hats blue.

b) How many hats did you colour red?

c) How many hats did you colour blue?

d) What part of the hats are not coloured?

Answer :

a) There are 15 hats in the given picture. Therefore,

1/3 of 15 = 1/3 X 15 = 5

Three-fifth of 15 = 3/5 X 15 =3X15/5 =9

So, colour 5 hats in red, and 9 hats in blue

b) Five hats are coloured in red.

c) Nine hats are coloured in blue.

d) One out of fifteen hats is not coloured. Therefore,1/15 hats are not coloured.

Question 1 :

Look at grid A again. Is the grid coloured:

a) 1/2 Blue ,1/2 white?

b) 2/4 Blue ,2/4 white?

c) 3/8 Blue ,3/8 white?

d) 4/8 Blue ,4/8 white?

Mark () on the wrong answer.

Answer :

Observe the grid A, it is coloured 8/16 blue, and 8/16 white.

Express 8/16 as equivalent fractions by dividing the numerator and denominator with the same number.

8/16 = 8#8/ 16#8 = 1/2

8/16 = 8#4/ 16#4 = 2/4

8/16 = 8#2/ 16#2 = 4/8

Therefore, the wrong answer is:

c) 3/8 Blue , 3/8 White ()

Question 2 :

Make different patterns by colouring some squares in the grids B, C, D. What part of the grid did you colour? What part of the grid remained white? Write.

Answer :

Do as directed. Answers may vary. A sample answer is:

Question 3 :

Draw grids of 16 squares and make patterns with

a) 2/8 red,1/2 yellow, 1/4 green

b) 3/16 red,5/16 yellow, 1/2 green

Answer :

a) Find the number of squares to be coloured in red, yellow, and green.

Number of red-coloured squares = 2/8 X 16 = 4

Number of yellow-coloured squares = 1/4 X 16 = 8

Number of green-coloured squares = 1/4 X 16 = 4

Therefore, draw a grid of 16 squares and colour 4 squares in the red, 8 squares in the yellow, and 4 squares in the green.

b) Find the number of squares to be coloured in blue, red, and green.

Number of blue-coloured squares = 3/16 X 16 = 3

Number of red-coloured squares = 5/16 X 16 = 5

Number of green-coloured squares = 1/2 X16 =8

Therefore, draw a grid of 16 squares and colour 3 squares in the blue, 5 squares in the red, and 8 squares in the green.

Question 1 :

Ramu wanted to give these vegetables to his friends. He gave Aboobacker one-fifth of these tomatoes and 1/3 of the potatoes. Srija got 2/5 of the tomatoes and 3/6 of 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

Answer :

There are 18 potatoes and 20 tomatoes in the given picture. See the given figure.

Step 1: Find the Aboobacker’s share as:

One-fifth of the tomatoes =1/5 X 20 = 20/5 = 4tomatoes.

1/3 of the potatoes = 1/3 X 18 =18/3 = 6 potatoes

Step 2: Find Srija’s share as:

2/5 of the tomatoes = 2/5 X 20 = 2 X 20/5 = 8 tomatoes

3/6 of the potatoes = 3/6 X 18 = 3 X 18/6 = 9 potatoes

Now, circle Aboobacker’s share in blue, and Srija’s share in yellow.

Since Nancy got the rest of the vegetables, count the vegetables that are not circled to find the share of Nacy.

Therefore, Nancy got 3 potatoes and 8 tomatoes.

Question 2 :

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 :

Observe the given picture. Ramu grows chillies, brinjals, tomatoes, spinach, and potatoes.

1) Observe the given picture. Out of 9 parts, tomatoes are in 3 parts. That is

3/9 = 1/3

Therefore, Ramu grows tomatoes in the biggest part of his field. That is one-third of the field.

2) The potatoes are in 2 out of 9 parts. That is 2/9 of the field.

Therefore, he grows potatoes in the two-ninth part of the field.

3) Spinach is in 1 out of 9 parts. Therefore, he grows spinach in the one-ninth part of the field.

Brinjals are in 2 out of 9 parts. Therefore, he grows brinjals in the two-ninth part of the field.

4) Do it by yourself. Answers may vary. A sample question is: Which vegetable grows in the smallest part of his field? What part?

2) Here the circle is divided into four equal parts. Out of four equal parts, two parts are coloured blue.

3) Here the circle is divided into six equal parts. Out of six equal parts, three parts are coloured blue.

4) Here the circle is divided into eight equal parts. Out of eight equal parts, four parts are coloured blue.

Therefore,1/2 = 2/4 = 3/6 = 4/8

Question 1 :

Ramesh bought a piece of halwa for his children Ammu and Anu.

He divided it equally for them.

a) Each will get ________ part of halwa.

d) What part of the halwa is each piece now?

e) If Ramesh had cut the halwa into 6 equal parts how many pieces each have got? Look at your answers and write:

1/2 = — = — = — = — = —

Answer :

a) Each will receive 1/2 part of halwa.

b) Since the halwa is divided into four equal pieces, Ammu will get two pieces. Since Amu will get 2 out of four pieces, it is 2/4 of the halwa.

c) Since the halwa is divided into eight equal pieces, each one will get 4 pieces.

d) Since the halwa is divided into eight equal pieces, each piece is 1/8 of the halwa.

e) If the halwa is divided into six equal pieces, then each one will get three pieces.

1/2 = 2/4 = 4/8 = 3/6 = 8/16 = 16/32

Answer :

a) The correct time for the train is quarter to seven, or 6 3/4 hours, but the train is late by half an hour. Therefore, the expected arrival time for the train is

6 + 3/4 + 1/2 = 24/4 + 3/2 + 2/4

= 29/4 =7 1/4

Hence, the expected arrival time for the train is quarter past seven. b) The expected arrival time of the train is 7 1/4 hours and Nazia gets off after 2 1/2 hours. Therefore, Nazia will get off at

7 1/4 + 2 1/2 = 7 1/4 +2 2/4 = 9 3/4 hours

Or quarter to nine.

c) Shaji will reach Ernakulam by this train after 5 hours. Expected time of the arrival of the train is 7 1/4 hours.

h) Make a bill of your own for vegetables you want to buy. Find the total money you will have to pay.

Answer :

a) Price of 1 kg tomato is Rs12. Therefore,

price of 2 kg tomato = 12 × 2 = Rs 24.

b) Price of 1 kg of tomato is Rs 12. Therefore,

price of 1/2 kg tomato = 1/2 X 12 = Rs 6

c) First convert 2 1/2 in fraction as:

2 1/2 = 2 x 2 + 1/2 = 5/2

The price of 1 kg tomato is Rs 12, Therefore,

price of 5/2 Kg tomato = 5/2 X 12 = Rs 30.

Hence, the price of 2 1/2 kg tomato is Rs 30.

d) First convert 3 1/2 in fraction as:

3 1/2 = 3 X 2 + 1 /2 = 7/2

The price of 1 kg potato is Rs 10. Therefore,

price of 7/2 kg of potato = 7/2 X 10 = Rs 35.

Hence, the price of 3 1/2 kg potato is Rs 35.

e) First convert 1 1/4 in fraction as:

1 1/4 = 1 X 4 + 1 / 5 = 5/4

The price of 1 kg carrot is Rs 18. Therefore,

price of 5/4 kg carrot = 5/4 X 18 = 22 1/2 = Rs 22.50

Hence, the price of 1 1/4 kg carrot is 22 rupees and 50 paise.

f) First convert 4 3/4 in fraction as:

4 3/4 = 4 X 4 + 3 / 4 = 19/4
