(iii) 63 rupees 9 paise = ₹6309/100 = ₹63.09
Question 2. Express as cm using decimals:
(i) 8 mm
(ii) 263 mm
(iii) 13 cm 3 mm
Answer:
(i) 8 mm = 8/10 cm = 0.8 cm

Question 3. Express as metres using decimals:
(i) 6 cm
(ii) 528 cm
(iii) 7 m 55 cm
Answer:
(i) 6 cm = 6/100 m = 0.06 m
(ii) 528 cm = 528/100 m = 5.28 m
(iii) 7 m 55 cm = 7 m + 55 cm
= 7 m + 55/100m = (7 + .55) m = 7.55 m
Question 4. Express as km using decimals:
(i) 5 m
(ii) 888 m
(iii) 15 km 88 m
Answer:
(i) 5 m = 5/1000 km = 0.005 km
(ii) 888 m = 888/1000 km = 0.888 km
(iii) 15 km 88 m = 15 km + 88 m
= 15 km + 88/1000 km = (15 + 0.88) kmsss
= 15.088 km
Question 5. Express as kg using decimals:
(i) 37 g

Question 7. Anita bought 2 m 70 cm cloth for her shirt and 2 m 85 cm cloth for her trouser. Find the total length of the cloth bought by her.
Answer:
Cloth bought for her shirt
= 2 m 70 cm = 2 m + 70 cm
= 2 m + 70/100m = 2 m + 0.70 m (∵ 1 cm = 1/100m)
= (2 m + 0.70) m = 2.70 m
Cloth bought for her trouser
= 2 m 85 cm = 2 m + 85 cm
= 2 m + 85/100m = 2 m + 0.85 m (∵ 1 cm = 1/100m)
= (2 + 0.85) m = 2.85
∴ Total lengths of cloth bought is 2.70 m + 2.85 m = 5.55 m
Question 8. Sunita travelled 15 km 268 m by bus, 7 km 7 m by car and 500 m on foot in order to reach her school. How far is her school from her residence?

Question 9. Rahul bought 4 kg 90 g apples, 2 kg 60 g grapes and 5 kg 300 g mangoes. Find the total weight of all the fruits he bought.
Answer:
Weight of apples = 4 kg 90 g
= 4 kg + 0.09 kg
= (4 + 0.09) kg = 4.09 kg
Weight of grapes = 2 kg 60 g
= 2kg + 60/1000 (∵ 1g = 1/1000 kg)
= 2 kg + 0.06 kg
= (2 + 0.06) kg = 20.6 kg
Weight of mangoes = 5 kg 300 g
= 5 kg + 300/1000 kg (∵1g = 1/1000 kg)
= 5 kg + 0.3 kg
= (5 + 0.3) kg = 5.3 kg
Total weight of his purchases is
= 4.090 kg + 2.060 kg + 5.300 kg
= 11.450 kg
