There are some division problems involving fractions that are pretty easy to do. For instance:

6/8 _____ 3/8How many 3/8 are there in 6/8? If we ask it this way, we can do this in our heads.

6/8 _____ = 2 3/8But what about something like

7/8 _____ = ? 3/5How many 3/5 are there in 7/8? Can you calculate that in your head? Some people would change the fractions to decimals and use a calculator (.825 divided by .6). Others would rewrite the fractions using common denominators.

(7/8) * (5/5) 35/40 35/40 40 35 _______________ = _______ = _______ * ____ = ____ (3/5) * (8/8) 24/40 24/40 40 24That's a pretty long process.

Use whatever method works best for you, but for many math students and teachers, "invert and multiply" is the strategy of choice.
