#### Question 1. Express as rupees using decimals:

(i) 75 paise
(ii) 1025 paise
(ii) 63 rupees 9 paise

(i) 75 paise = ₹75/100 = ₹0.75
(ii) 1025 paise = ₹1025/100 = ₹10.25
(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

(i) 8 mm = 8/10 cm = 0.8 cm
(ii) 263 mm = 263/10 cm = 26.3 cm
(iii) 13 cm 3 mm = 13 cm × 3/10 cm = 13.3 cm

#### Question 3. Express as metres using decimals:

(i) 6 cm
(ii) 528 cm
(iii) 7 m 55 cm

(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

(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
(ii) 100 g
(iii) 5 kg 8 g

(i) 37g = 37/1000 kg = 0.037 kg
(ii) 100 g = 100/1000kg = 0.1 kg
(iii) 5kg 8g = 5kg + 8gm
= 5 kg = 8/1000kg.
= (5 + .008) kg = 5.008 kg

#### Question 6. Express as kL using decimals:

(i) 6L

(ii) 555L

(iii) 3 kL 95L

(i) 6L = 6/1000 = 0.006 kL

(ii) 555L = 555/1000 = 0.555kL

(iii) 3 kL 95L = 3 + 95/1000 = 3.095 kL

#### 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.

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?

Distance travelled by bus
= 15 km 268 m = 15 km + 268 m
= 15 km + 268/1000 km

= 15 km + 0.268 km

#### 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.

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

#### Question 10. Rani had ₹18.50. She bought one ice¬cream for ₹11.75. How much money does she have now?

Money Rani had = ₹ 18.75
Ice-cream bought for ₹11.75
∴ Money she has now = ₹ 18.50 – ₹ 11.75 = ₹ 6.75

#### Question 11. Tina had 20 m 5 cm long cloth. She cuts 4m 50 cm length of cloth from this for making a curtain. How much cloth is left with her?

Length of cloth cut of 4 m 50 cm
= 4 m + 50 cm

#### Question 12. 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?

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
= 2620/1000 = 2 kg 620 gm ⇒ 2.620 kg

#### Question 13. The cost of 1 metre of cloth is ₹35.80. What will be cost of 9.8 metres of cloth?
