Multiplying Mixed Numbers

Recap:

• Step 1: Convert mixed numbers to improper fractions using the MAD method.

• Step 2: Improper Fractions are then multiplied straight across to create a new fraction.

• Step 3: Simplify your new fraction if needed (or wait until the end)

• Step 4: Complete your problem by dividing your numerator by the denominator
