Example 19: Divide 20 kg 196 g by 6. 3366
Solu on: 20 kg 196 g = (20 × 1,000) g + 196 g 6 20196

= 20,000 g + 196 g = 20,196 g –18
21
Now divide 20,196 g by 6.
– 18
20,196 g  6 = 3,366 g
39
3,366 g = 3 kg 366 g – 36

So, the quo ent obtained is 3 kg 366 g. 36

Example 20: Navya has a packet of chocolates weighing 1 kg 752 g. What will be the weight
of 9 such packets?
Calcula on
Solu on: Weight of 1 packet = 1 kg 752 g = 1,752 g
6 4 1
Weight of 9 packets = 9 × 1,752 g = 15,768 g 1 7 5 2

= 15 kg 768 g × 9
So, the weight of 9 packets of chocolates will be 1 5 7 6 8
15 kg 768 g.

Example 21: The weight of 4 boxes is 32 kg. Find the weight of each box.
Calcula on
Solu on: Weight of 4 boxes = 32 kg 8

 Weight of 1 box = 32 kg  4 = 8 kg 4 32
– 32
So, the weight of each box is 8 kg.
