The colour orange can be made by mixing 5 litres of yellow paint with 8 litres of red paint.

If 140 litres of yellow paint are used in this mixture, how much red paint is needed?

Worked Solution

Let  x\ \large x = litres of red paint needed
58\dfrac{5}{8} = 140x\dfrac{140}{\large x}
5x5 \large x = 140 ×\times 8
x\large x = 140×85\dfrac{140 \times 8}{5}
= 224 litres
