**PJ**, Monday, April 26, 2010 at 1:36pmYou can "reduce" before you multiply if you can find a factor of one numerator and the other denominator.

11/52 X 39/80 52 and 39 are both divisible by 13, making your problem

11/4 X 3/30

21/25 X 15/28 21 and 28 both divisible by 7; 15 and 25 are divisible by 5, making the problem 3/5 X 3/4

Your answer should be the same either way. It just makes it easier in the end.
