It is point G, because that is where the 3 angle bisectors meet.
Simple proportions.
You want a 1:5 ratio.
You have a 5:1 ratio.

5:25 = 1:5
or
5/x = 1/5 and cross multiply.
9 out of 12 = 9/12 which can be simplified to 3/4. So the team wins 3/4 of its games. 3/4 of 64 = 64 divided by 4 = 16. 16 x 3 = 48.
