**Lynn**, Saturday, July 10, 2010 at 9:14pmThank you, but how do I determine what number to divide by? So that I an solve other fractions like this one. Must I still find the greatest common number to divide by?

**Ms. Sue**, Saturday, July 10, 2010 at 9:55pmYes. You find the largest common divisor to reduce a fraction.

Example?

10/15

Divide by 5

10/15 = 2/3

**Quidditch**, Sunday, July 11, 2010 at 12:23amBe careful. You posted (72)/(-68) reduces to (-18)/(-17). You had a sign change in the numerator. Probably just a typo, but you might want to check.
