How to simplify 45/50

First, find the GCF, or greatest common factor. (That's the number that if you multiply it by another, you get that number; 3 is a factor of 6 because 3x2 is 6)

The GCF is 5. Now divide both numbers by five. You get 9/10.

Well you would see if any number goes into 45 and 50.
