6th Maths: Term 2 Unit 2

Measurements - Exercise 2.1

1. Fill in the blanks

(i) 250 ml + ½ l = ¾ l Solution: 250 ml = ¼ l + ½ l = ¾ l

(ii) 150 kg 200 g + 55 kg 750 g = 205 kg 950 g

(iii) 20 l – 1 l 500 ml = 18 l 500 ml

(iv) 450 ml × 5 = 2 l 250 ml Solution: 450 ml × 5 = 2250 ml ÷ 1000 = 2l 250 l

(v) 50 kg ÷ 100 g = 500g

Solution: 50 kg (50000/100) = 500 g

2. True or False

(i) Pugazhenthi ate 100 g of nuts which is equal to 0.1 kg. [True]

(ii) Meena bought 250 ml of buttermilk which is equal to 2.5 l. [False]
(250 ml ÷ 1000 = 0.250l)

(iii) Karkuzhali’s bag 1 kg 250 g and Poongkodi’s bag 2 kg 750 g. The total weight of their bags 4 kg. [True]

(iv) Vanmathi bought 4 books each weighing 500 g. Total weight of 4 books is 2 kg. [True]

(v) Gayathri bought 1 kg of birthday cake. She shared 450 g with her friends. The weight of cake remaining is 650 g. [False]
[1 kg 000g ] – [0kg 450 g] = 0kg 550g

3. Convert into indicated units:

(i) 10 l and 50 ml into ml 10l 50 ml = (10 × 1000) ml + 50 ml. (1 l = 1000 ml) = 10000 ml + 50 ml = 10050 ml

(ii) 4 km and 300 m into m 4 km 300 m = (4 × 1000) m + 300 m (1 km = 1000 m) = 4000 m + 300 m = 4300 m

(iii) 300 mg into g 300 mg = 300 ÷ 1000 g (1000 mg = 1 g) = 0.3 g

4. Convert into higher units:

(i) 13000 mm (km, m, cm) 13000 mm = (13000 ÷ 10) cm = 1300 cm (10mm = 1 cm)
13000 mm = (13000 ÷ 1000) m = 13 m (1000 mm = l m)
13000 mm = (13000 ÷ 1000000) km = 0.013 km (1000000 mm = 1 km)

(ii) 8257 ml (kl, l) 8257 ml = (8257 ÷ 1000) l = 8.257 l (1000 ml = 1 l )
8257 ml = (8257 ÷ 1000000) kl = 0.008257 kl (1000000 ml = 1 kl)

Word Problems & Applied Math

7. Geetha brought 2 l and 250 ml of water in a bottle. Her friend drank 300 ml from it. How much of water is remaining in the bottle? Water in a bottle = 2l 250 ml

8. Thenmozhi’s height is 1.25 m now. She grows 5 cm every year. what would be her height after 6 years? Thenmozhi’s height now = 1.25 m = 125 cm
Height she grows in one year = 5 cm
Height she grows in 6 years = 6 × 5 = 30 cm
After 6 years her height = Now her height + 30 cm = (125 + 30) cm = 155 cm
