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
Y=3 because it is horizantal line that is between 0 and 6
