A + B - A&B must equal 1 here.
2/3 + 3/5 - X = 1
10/15+ 9/15 - x = 15/15
-x = -4/15
x = 4/15
Subtract this from the total golf number:
10/15 - 4/ 15 = 6/15 or 2/5
2/5 of 200 = 80
(Note: this question is a bit off though because 2/3 of 200 would give you a fraction and you can't have a fraction of a person)
