In order to solve this problem, we need our knowledge on ratio and proportion for us to set up an equation. A proportion is an equation with a ratio on each side. It is a statement that two ratios are equal. We do as follows:

7 parts water / 1 part lemon = 4 quarts - x / x

where x is the quarts lemon needed

Solving for x,

x = 0.5

water needed = 4-x = 3.5 quarts water is needed
