Question

Convert into indicated units:

(i) 10 l and 5 ml into ml

(ii) 4 km and 300 m into m

(iii) 300 mg into g

Answer 1

(i) 10 l and 5 ml

= 10 × 1000 ml + 5 ml

= 10,000 ml + 5 ml [∴ 1l = 1000 ml]

= 10,005 ml.

∴ 10 l and 5 ml = 10,005 ml.

(ii) 4 km and 300 m into m.

4 km and 300 m

= 4 × 1000 m + 300 m

= 4000 m + 300 m [∴ 1 km = 1000 m]

= 4300 m

∴ 4 km and 300 m = 4300 m

(iii) 300 mg into g.
