I'm writing a function for a web app that looks at all of a student's scores, and determines the score that if dropped, will give the student the highest possible grade. It's fairly simple to do in a bruteforce way by iterating through every combination, but I'm wondering if there is a simpler, mathematical way to determine which one should be dropped. Example scores: 2/3, 3/5, 6/10, 80/100. Total grade is the sum of the numerators divided by the sum of the denominators. Been racking my brains on this one.

(2 + 3 + 6 + 80) / (3 + 5 + 10 + 100) = 91/118 = .77 Are you SURE?
