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 + \frac{70}{100}m = 2 m + 0.70 m (∵ 1 cm = \frac{1}{100}m)
= (2 m + 0.70) m = 2.70 m

Cloth bought for her trouser
= 2 m 85 cm = 2 m + 85 cm
= 2 m + \frac{85}{100}m = 2 m + 0.85 m (∵ 1 cm = \frac{1}{100}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
ML Aggarwal Class 6 Solutions for ICSE Maths Chapter 7 Decimals Ex 7.5 3
= 4 kg + 0.09 kg
= (4 + 0.09) kg = 4.09 kg
Weight of grapes = 2 kg 60 g
= 2kg + \frac{60}{1000} (∵ 1g = \frac{1}{1000} kg)
= 2 kg + 0.06 kg
= (2 + 0.06) kg = 20.6 kg
Weight of mangoes = 5 kg 300 g
= 5 kg + \frac{300}{1000} kg (∵1g = \frac{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

Question 9.

Question 11.
Ruby bought a watermelon weighing 5 kg 300 g. Out of which she gave 2 kg 680 g to her neighbour. What is the weight of the watermelon left with Ruby?

Answer

Total weight of watermelon = 5 kg 300 gm
∴Given to neighbour = 2 kg 680 gm
∴ Weight of watermelon left = 5 × 1000 + 300 gm – 2 × 1000 gm + 680 gm
= 5300 gm – 2680 gm = 2620 gm
\frac{2620}{1000} = 2 kg 620 gm ⇒ 2.620 kg

Question 12.

Cost of 6 tickets = ₹ 150 × 6 = ₹ 900
Cost of 1 cold drink = ₹28.50
Cost of 6 cold drinks = ₹28.50 × 6 = 171

Question 9

Ravi purchased 5 kg 400 g rice, 2 kg 20 g sugar and 10 kg 850 g flour (aata). Find the total weight of his purchases.

Answer

Weight of rice purchased
= 5 kg 400 g = 5 kg + 400 g
= 5 kg + \frac{400}{1000} kg [∵ 1 g = \frac{1}{1000} kg] = 5 kg + 0.400 kg
= (5 + 0.400) kg = 5.400 kg
Weight of sugar purchased
= 2 kg 20 g = 2 kg + 20 g
= 2 kg = \frac{20}{1000} kg [∵ 1 g = \frac{1}{1000} kg] = 2 kg + 0.020 kg = 2.020 kg
Weight of flour purchased
= 10 kg 850 g = 10 kg + 850 g
= 10 kg + \frac{850}{1000} kg [∵ 1 g = \frac{1}{1000} kg] = 10 kg + 0.850 kg
= (10 + 0.850) kg = 10.850 kg
∴ Total weight of his purchases is
