In a box, there are 2 red apples and 3 green apples. There are ____ more green apples than red apples. Give your answer as a fraction.

To find the number of green apples more than red apples, subtract the number of red apples from the number of green apples. In this case, there are 3 green apples and 2 red apples. So, 3 - 2 equals 1. Therefore, there is 1 more green apple than red apple.

To express this as a fraction, represent the difference (1) as a fraction with the denominator being the total number of red apples (2). Thus, the fraction is 1/2.
