Procedure to multiply fractions: Let’s try to multiply a polynomial by another polynomial Procedure to multiply fractions: 1. Factor, when possible, the numerators and denominators of the fractions. 2. Reduce both the numerator and denominator. 3. Multiply the remaining factors of the numerators. 4. Multiply the remaining factors of the denominators.

Factor both fractions 1 Cancel as many as possible 2x Multiply the denominators and numerators

Multiply:

Divide: To divide fractions, we first need to change division to multiplication and flip over the 2nd fraction 2 1
