If you have 1 gallon of water minus 2 cups and then add 2 cups of fresh lemon juice how much lemon juice would you put in 1 quart of water?

Answer 1

Take 1 cup as 1/2 a pint, 2 cups = 1 pint

>

Ratio of juice : water = 1 : 7 = 12.5% juice

>

So if: 1 quart = 87.5% (0.875)

Then : x quart = 12.5% (0.125)

>

Then x = 1 / 7 quarts = 0.142857 quarts

= 135.19 ml (if quarts US)

= 162.36 ml (if quarts UK)
