Question

Express as kilogram (kg) using decimals:

(i) 8 g
(ii) 150 g
(iii) 2750 g
(iv) 5 kg 750 g
(v) 36 kg 50 g

Answer 1

(i) 8 g
We know that 1000 g = 1 kg.
Therefore, 1 g = 1/1000= 0.001 kg.
8 g = 8/1000= 0.008 kg

(ii) 150 g
We know that 1000 g = 1 kg.
Therefore, 1 g = 1/1000= 0.001 kg.
150 g = 150/1000 = 0.150 kg

(iii) 2750 g
We know that 1000 g = 1 kg.
Therefore, 1 g = 1/1000= 0.001 kg.
2750 g = 2.750 kg

(iv) 5 kg 750 g
We know that 1000 g = 1 kg.
Therefore, 1 g = 1/1000= 0.001 kg.
5 kg 750 g = $5+\frac{750}{1000}$
=5.750 kg

(v) 36 kg 50 g
We know that 1000 g = 1 kg.
Therefore, 1 g = 1/1000= 0.001 kg.
36 kg 50 g = $36+\frac{50}{1000}$
= 36.050 kg
