**4. Practice time**

**(A) 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? Write here.**

**Solution:-**

Manju had a chocolate.

Number of bites in the chocolate is 12.

She gave one-fourth of it to raji = ¼ × 12

= 3 bites

Sugatha got one-third of it = (1/3) × 12

= 4 bites

Sheela got one-sixth of it = (1/6) × 12

= 2 bites

**(i) What part of the chocolate did Manju eat? **

**Solution:-**

Part of the chocolate remains with manju = 12 – (3 + 4 + 2)

= 12 – 9

= 3 bites

Therefore, Manju eat 3 bites of chocolate.

**(B) Colour the hats**

**(i) Colour 1/3 of the hats red. **

**(ii) Colour three-fifth hats blue.**

**(iii) How many hats did you colour red? **

**(iv) How many hats did you colour blue? **

**(v) What part of the hats are not coloured?**

**Solution:-**

The total number of hats in the given figure = 15

**(i) **Out of 15 colour 1/3 of the hats red = 1/3 × 15

= 5 hats

**(ii) **Out of 15 colour three-fifth hats blue = 3/5 × 15

= 3 × 3

= 9 hats

**(iii)** 5 hats are coloured red.

**(iv) **9 hats are coloured blue.

**(v) **Number of hats coloured = 14

Total number of hats = 15

So, Number of hats not coloured = 15 – 14

= 1 hat

Therefore, (1/15)^{th} part of the hats are not coloured.

Patterns in parts Page: 57

**1) 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.**

**Solution:-**

**2) Look at grid A again. Is the grid coloured—**

**(a) ½ blue, ½ white? (b) 2/4 blue, 2/4 white?**

**(c) 3/8 blue, 5/8 white? (d) 4/8 blue, 4/8 white?**

**Mark (X) on the wrong answer.**

**Solution:-**

(a) ½ blue, ½ white (b) 2/4 blue, 2/4 white

(c) 3/8 blue, 5/8 white (X) (d) 4/8 blue, 4/8 white

Because,

(a) ½ blue, ½ white = 8/16 = ½ … [divide both denominator and numerator by 8]

(b) 2/4 blue, 2/4 white = 8/16 = 2/8 … [divide both denominator and numerator by 4]

(d) 4/8 blue, 4/8 white = 8/16 = 4/8 … [divide both denominator and numerator by 2]

**3) Draw grids of 16 squares and make patterns with**

**(a) 2/8 red, ½ yellow, ¼ green**

**(b) 3/16 blue, 5/16 red, ½ green**

**Solution:-**

(a) 2/8 red, ½ yellow, ¼ green

Out of 16 squares 2/8 red = 2/8 × 16

= 2 × 2

= 4 red squares

Out of 16 squares ½ yellow = ½ × 16

= 1 × 8

= 8 yellow squares

Out of 16 squares ¼ green = ¼ × 16

= 1 × 4

= 4 green squares

(b) 3/16 blue, 5/16 red, ½ green

Out of 16 squares 3/16 blue = 3/16 × 16

= 3 × 1

= 3 blue squares

Out of 16 squares 5/16 red = 5/16 × 16

= 5 × 1

= 5 red squares

Out of 16 squares ½ green = ½ × 16

= 1 × 8

= 8 green squares

Ramu’s vegetable field Page: 58

**Ramu’s vegetable field has 9 equal parts. **

**1. What vegetables does he grow?**

**Solution:-**

Ramu grows chillis, potatoes, brinjals, tomatoes and spinach in his vegetable field.

**i) Which vegetable grows in the biggest part of his field? What part?**

**Solution:-**

He grows tomato in the biggest part of the field.

Out of 9 equal parts 3 of them contains tomato i.e. (3/9)^{th} part of his field contains tomato.

**ii) On what part of the field does he grow potatoes?**

**Solution:-**

Out of 9 equal parts 2 of them contains potato.

So, (2/9)^{th} part of his field contains potato.

**iii) What part of the field is used to grow spinach? What part is used for brinjals? **

**Solution:-**

Out of 9 equal parts only one part contains spinach.

So, (1/9)^{th} part of his field contains spinach.

Out of 9 equal parts 2 parts contains brinjals.

So, (2/9)^{th} part of his field contains brinjals.

**2. 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.**

**Solution:-**

From the given figure,

Total number of potatoes = 18

Total number of tomatoes = 20

From the question,

Ramu wanted to give these vegetables to his friends.

Aboobacker got one-fifth of these tomatoes = (1/5) × 20

= 1 × 4

= 4

Aboobacker got 1/3 of the potatoes = (1/3) × 18

= 1 × 6

= 6

Srija got 2/5 of the tomatoes = (2/5) × 20

= 2 × 4

= 8

Srija got 3/6 of the potatoes = (3/6) × 18

= 3 × 3

= 9

Then,

Nancy got the rest of these vegetables.

Total number of vegetables including potatoes and tomatoes = 20 + 18

= 38

Number of vegetables got by Aboobacker and Srija = 4 + 6 + 8 + 9

= 27

So, Nancy got = 38 – 27

= 11 vegetables.

**(i) How many potatoes and tomatoes did Nancy get?**

**Solution:-**

From the above solution,

Total number of tomatoes = 20

Total number of potatoes = 18

Then,

Number of tomatoes got by Aboobacker and Srija = 4 + 8

= 12

Number of potatoes got by Aboobacker and Srija = 6 + 9

= 15

Now,

Number of tomatoes got by Nancy = 20 – 12

= 8 tomatoes

Number of potatoes got by Nancy = 18 – 15

= 3
