You don't need a common denominator to multiply or divide fractions.

To multiply fractions, multiply the numerators and the denominators, e.g.:

1/2 x 3/5 = (1/3) / (2/5) = 3/10

To divide fractions, multiply the first fraction with the reciprocal of the second.

1/2 divided by 5/3 is the same as 1/2 times 3/5.
