Question

A man spent one fifth of his money at the butchers and one third of his money at the supermarket. He had £5.60 left. How much did he start with?

Answer 1

$\frac{1}{5}$ spent at the butchers

$\frac{1}{3}$ spent at the supermarket

Calculate what fraction of the money was left:

$1 - ( \frac{1}{5} + \frac{1}{3} ) =$ $\frac{7}{15}$

$\frac{7}{15}$ $x =$ 5.60

$x =$ 12

Therefore the starting amount was 12 pounds
