james wants to make cookies if he has 4/5 cups of sugar and the recipe uses 2/5 cups of sugar how much sugar dose he have left

To find out how much sugar James has left after using 2/5 cups for the recipe, we need to subtract the amount used from the initial amount he had.

To subtract fractions, we need to have a common denominator. In this case, the denominators are already the same (both 5). So, we can subtract the numerators directly.

First, let's subtract:

4/5 - 2/5

To do this, subtract the numerators while keeping the denominator the same:

(4 - 2)/5

This simplifies to:

2/5

So, James has 2/5 cups of sugar left.
