Answer:

Ava needs to add 50ml of cleaner.

Step-by-step explanation:

Ratio of cleaner : water = 1:7

This means that the total ratio;(water+cleaner) = 1+7 = 8

Find fraction of each item out of the total ratio of 8;

Fraction of water = \frac{7}{8}

Fraction of cleaner = \frac{1}{8}

Knowing the fractions, find the quantity of cleaner in <em>ml </em>out of a total of 400-ml;

Cleaner = (1/8 )*400 = 50ml

Therefore, Ava needs to add 50ml of cleaner.
