Question

Trilly went to a market to buy mangoes. She bought 15 mangoes.
If the weight of 1 mango is $1\frac{1}{3}\text{kg}$ , find the weight of 15 mangoes.

Answer 1

Weight of 1 mango = $1\frac{1}{3}\text{kg}$
Converting $1\frac{1}{3}$into improper fraction:
$1\frac{1}{3}=\frac{1\times 3+1}{3}1\frac{1}{3}=\frac{4}{3}$
Weight of 15 mangoes = $15\times \frac{4}{3}$
Weight of 15 mangoes = $\frac{60}{3}\text{or}20$
So, the weight of 15 mangoes is 20 kg.
