Express in kg:
(i) 200 g (ii) 3470 g (iii) 4 kg 8 g
Solution:
We use the basic concepts of fractions to answer the question given.
We solve the above question by representing the part as a fraction of the whole.
(i) 200 g
∵1000g =1 kg
∴1g = 1/1000 kg
Hence, 200 g = 200 × 1/1000 kg
= 200/1000 kg
= 0.2 kg
(ii) 3470 g
∵1000g = 1 kg
∴1g = 1/1000 kg
3470 g = 3470 × 1/1000 kg
3470 g = 3470/1000 kg
= 3.47 kg
(iii) 4 kg 8 g
4 kg 8 g = 4 kg + 8 g
∵1000 g =1 kg
∴ 1g = 1/1000 kg
4 kg 8 g = 4 kg + 8 × 1/1000 kg
4 kg 8 g = 4 kg + 0.008 kg
4 kg 8 g = 4.008 kg
