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 =
Fraction of cleaner =
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.
