Answer:

7 9/14

Step-by-step explanation:

The girls ate 8 1/7 of a pie, so we mark G=8 1/7

The boys ate 1/2 of a pie, so we mark B=1/2

The girls ate the more pies, so we do this:

G-B

We plug the G and the B in, and it is 8 1/7-1/2

We change it to the common denominator, which is 14. We have 8 2/14- 7/14

we take a one and add 14 to 2 and we have this:

7 16/14-7/14

and that equals 7 9/14
