Question 6: A family consumes 32 kg 250 g of wheat and 18 kg 600 g of rice in a month. Find the difference in consumption of wheat and rice.

Wheat consumed = 32 kg 250 g

Rice consumed = 18 kg 600 g

Difference in consumption of wheat and rice = 32 kg 250 g – 18 kg 600 g

Hence, required difference is 13 kg 650 g

Question 7: Mohan covered a distance of 15 km 275 m in the first hour and 18 km 803 m in the second hour. What distance did he cover in two hours?

Distance covered in first hour = 15 km 275 m.

Distance covered in second hour = 18 km 803 m

Total distance covered in 2 hours

= 15 km 275 m + 18 km 803 m

= 33 km + 1,000 m + 78 m = 34 km 78 m.

Hence, Mohan covered 34 km 78 m in two hours.

Question 8: Subtract :

(a) 7 km 207 m from 16 km 112 m

(b) 10 m 72 cm from 42 m 63 cm

(c) 26 kg 432 g from 51 kg 307 g

(d) 11 l 853 ml from 44 l 92 ml

Question 9: Add :

(a) 10 km 525 m and 15 km 895 m

 

= 25 km + 1,000 m + 420 m

= 25 km + 1 km + 420 m

= 26 km 420 m.

(b) 52 g 925 mg and 36 g 125 mg

 

= 88 g + 1,000 mg + 50 mg

= 88 g + 1 g + 50 mg = 89 g 50 mg.

(c) 16 kl 256 l and 27 kl 903 l

 

= 43 kl + 1,000 l + 159 l

= 43 kl + 1 kl + 159 l = 44 kl 159 l.

(d) 71 cm 9 mm, 26 cm 3 mm and 9 mm.

 

= 97 cm + 20 mm + 1 mm

= 97 cm + 2 cm + 1 mm = 99 cm 1 mm.

Question 10: 7410 ml soup was made. It was equally distributed among 6 persons. How much soup was given to each person?

Total quantity of soup = 7410 ml = 7.410 l 

Number of persons = 6

Soup given to each person = 7.410 ÷ 6 = 1.235 l 

Hence, each person gets 1.235 l = 1235 ml soup.

Question 11: The length of ribbon required for making a design is 4 m 16 cm. What is the length of the ribbon required for making 8 such designs?

Length of ribbon required for 1 design = 4 m 16 cm

Number of designs = 8

Total length of ribbon required = 4 m 16 cm × 8

Hence, required length of ribbon = 33 m 28 cm.

Question 12: Divide :

(a) 6 kg 128 g by 4

We can do the divisions by decimal notation as it is easier.

6 kg 128 g = 6.128 kg

Thus, Q uotient = 1.532 kg = 1 kg 532 g

Hence, 6 kg 128 g ÷ 4 = 1 kg 532 g.

(b) 7 m 53 cm by 3

7 m 53 cm = 7.53 m

Thus, quotient = 2.51 m = 2 m 51 cm

Hence, 7 m 53 cm ÷ 3 = 2 m 51 cm.

(c) 7 l 52 ml by 4

7 l 52 ml = 7.052 l

Thus, quotient = 1.763 = 1 763 ml

Hence, 7 52 ml = 1 763 ml.

Question 13: Multiply :

(a) 4 km 365 m by 6

  

= 24 km + 2,000 m + 190 m

= 24 km + 2 km + 190 m

= 26 km 190 m.

in decimal notation

= 26 km 190 m.

(b) 5 214 ml by 8

= 40 + 1,000 ml + 712 ml

= 40 + 1 + 712 ml = 41 712 ml

in decimal notation

= 41 712 ml.

(c) 18 kg 615 g by 5

= 90 kg + 3,000 g + 75 g

= 90 kg + 3 kg + 75 g = 93 kg 75 g.

in decimal notation

= 93 kg 75 g.

(d) 18 cm 6 mm by 9

= 162 cm + 50 mm + 4 mm

= 162 cm + 5 cm + 4 mm

= 167 cm 4 mm.

in decimal notation
