Question 6.

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 + m = 2 m + 0.70 m (∵ 1 cm = m)

= (2 m + 0.70) m = 2.70 m

Cloth bought for her trouser

= 2 m 85 cm = 2 m + 85 cm

= 2 m + m = 2 m + 0.85 m (∵ 1 cm = m)

= (2 + 0.85) m = 2.85

∴ Total lengths of cloth bought is 2.70 m + 2.85 m = 5.55 m

Question 8.

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 + (∵ 1g = kg)

= 2 kg + 0.06 kg

= (2 + 0.06) kg = 20.6 kg

Weight of mangoes = 5 kg 300 g

= 5 kg + kg (∵1g = 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
