To divide fractions, what we really do is multiply by the reciprocal.

For example:

  b            a     d
-----   =     --- * ---
  c            b     c

so 1/2  /   3/4

is equal to:

 1     4
--- * ---
 2     3

To multiply fractions, we just multiply straight across:


and that reduces to 


I hope this helps you.
