Exercise 4.1

1. Fill in the blanks:

(i) 7 kg 400 g = 7400g

(ii) 5g 50mg = 5050 mg

(iii) 9500 mg = 9 g 500 mg

(iv) 15 kg 350g = 15350 g

(v) 6250g = 6 kg 250 g

(i) 4 kg 250 g + 3 kg 450 g

4 kg  250 g +

3 kg  450 g

7kg  700g

(ii) 75 g 430 mg + 750 g.

75 g  430 mg +

750g  000 mg

825g  430mg

(iii) 97 kg 45 g + 77 kg 450 g + 33 kg 250g

97 kg 450 g +

77 kg 450 g

33 kg 250g

207kg 745g

(iv) 75 kg 400 g + 30 kg 250 g

75 kg 400 g +

30 kg 250 g

105 kg 650 g

3. Subtract the following:

(i) 40 kg 350 g − 25 kg 200 g

40 kg 350 g –

25 kg 200 g

15 kg 150 g

(ii) 35 kg 850 g − 18 kg 500 g

35 kg 850 g −

18 kg 500 g

17 kg 350 g

(iii) 985 kg 475 g − 275 kg 325 g

985 kg 475 g –

275 kg 325 g

710 kg 150 g

(iv) 700 kg − 300 kg 500 g

700 kg 000 g –

300 kg 500 g

399 kg 500 g

4. Multiply the following:

(i) 4 kg 300 g × 7

4 kg 300 g × 7 = 30kg 100 g

(ii) 17 kg 750 g × 8

17 kg 750 g × 8 = 142 kg

(iii) 25 kg 550 × 4

25 kg 550 × 4 = 102 kg 200g

(iv) 72 g 350 mg × 5

72 g 350 mg × 5 = 361g 750 mg

5. Divide the following:

(i) 99 kg 990 g ÷ 3

99 kg 990 g ÷ 3 = 33 kg 330g

(ii) 147 g 630 mg ÷ 7

147 g 630 mg ÷ 7 = 21g 090mg

(iii) 550 kg 220 g ÷ 11

550 kg 220 g ÷ 11 = 50kg 020g

(iv) 484 g 384 mg ÷ 4

484 g 384 mg ÷ 4 = 121g 096 mg

6. What is the total weight of 7 kg 500g of cashew nut and 3 kg 350g of pista?

Weight of cashewnut = 7 kg 500 g +

Weight of Pista            = 3 kg 350 g

10 kg 850 g

7. Vimal had a sack of cotton seeds weighing 50kg 350g. He used 7 kg 300g cotton seeds to feed his cow. How much cotton seed will be remaining after feeding his cow?

Weight of cotton seeds Vimal had = 50 kg 350 g

Weight of cotton seeds used            = 7 kg 300 g

Remaining cotton seeds                   = 43 kg 050 g

Remaining cotton seeds = 43 kg 050 g

8. A glass bottle can contain 25 g 125 mg of medicine, how much medicine can 7 such bottles contain?

One bottle contains medicine = 25g 125mg

7 bottles contain medicine =

7 bottles contain medicine = 175 g 875mg

9. 75 kg 750 g of groundnut seed is filled in five bags, how much groundnut seed can a bag contain?

5 bags contain groundnut seeds = 75kg 750g

One bag contains groundnutseeds = 75kg 750g ÷ 5

One bag contains groundnut seeds = 15kg 150g
