To multiply fractions, all you have to do is multiply the numerators and denominators and simplify the result. To divide fractions, you simply have to flip the numerator and denominator of one of the fractions, multiply the result by the other fraction, and simplify.
Example 1 â Divide: 1  Step 1: To divide complex numbers, you must multiply by the conjugate. 2  Step 2: Distribute (or FOIL) in both the numerator and denominator to remove the parenthesis. 3  Step 3: Simplify the powers of i, specifically remember that i2  = â1.
