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.

What is the greatest common denominator of 24 and 36?
There can be no greatest common denominator. For supose x is the greatest common denominator. ie 24 divides x and 36 divides x. Then 2x is a common denominator and 2x > x so 2x is a greater common denominator than the greatest common denominator. That contradiction implies that there is no greatest common denominator.

How do you simplify with complex fractions?
To simplify complex fractions, first rewrite the complex fraction as a division of two fractions. Identify the numerator and denominator, and if necessary, find a common denominator for the fractions involved. Then, multiply both the numerator and the denominator by that common denominator to eliminate the fractions. Finally, simplify the resulting expression by reducing any common factors.
