Number theory question
I was solving a problem, but I couldn't do it. So I looked at the editorial, in witch this was given:
(X + Y) / (A + B) <= MAX{X / A, Y / B}
where X, Y, A, B >= 0 and are integers.
So my question is, what is the proof to that? Sorry for the stupid question, but I couldn't find this anywhere.
