Question

(i) Weight of one apple is 400 g. Find the weight of 12 apples.
(ii) Number of apples in 4 kg

Answer 1

(i) Weight of one apple = 400 g
Weight of 12 apples=12 $\times$ 400 g = 4800 g = 4.8 kg
(ii) 1 kg = 1000g
4 kg =4 $\times$ 1000 g = 4000g
Weight of one apple= 400 g
Number of apples $=\frac{totalweight}{weightofoneapple}=\frac{4000g}{400g}=10apples$
