What fraction of 1 gallon is 5 cup?

Answer 1

There are four quarts to a gallon, two pints to a quart and two cups to a pint. That is 16 cups to a gallon. So it would be 5/16.
A cup equals one half pint. There are two pints in a quart, and four quarts in a US gallon.

So, we have to do a little arithmetic: (4 * 2) * 2 = 16

There are then 16 cups to a gallon. So, five cups to a gallon is 5/16 or .3125, so .003125% of a gallon.

More than you requested, but should cover your question.
