Question

In a fruit cocktail, for every 15 ml of orange juice you need 25 ml of apple juice and 10 ml of coconut milk. What proportion of the cocktail is coconut milk? Give your answer as a fraction in its simplest form.

Answer 1

If you sum the amounts of each ingredient, you have a total of

$15+25+10 = 50$

So, the whole cocktail is 50ml. Of these, 10 are coconut milk. So, the ratio coconut : total is

$\dfrac{10}{50} = \dfrac{1}{5}$

Answer 2

$\frac{coconut}{total} = \frac{10}{15 + 25 + 10} = \frac{10}{50} = \frac{1}{5}$
