Dividing the Complex Fraction
Divide .
Because a fraction bar represents division, a complex fraction is simply another way of writing the division of two fractions.
Step 1 — Rewrite with a division sign. The main fraction bar separates the numerator fraction from the denominator fraction:
Step 2 — Rewrite as the product of the first fraction and the reciprocal of the second:
Step 3 — Factor the numerators and denominators, then multiply. Factor each polynomial:
The expression becomes:
Step 4 — Simplify by dividing out common factors. Cancel the shared factors , , and :
This example shows that when a division of rational expressions is written as a complex fraction (one fraction stacked over another), the first step is to rewrite the main fraction bar as a division sign. From there, the standard procedure applies: multiply by the reciprocal, factor, and cancel.
