# Simplifying Fractions before Multiplying

## Big Idea:

By simplifying fractions before we multiply, we make the multiplication easer and leave the answer in its simplest form. (Also called pre-reducing.)

#### Remember:

You can save work in some multiplication problem by simplifying before you multiply.

 Step 1. Take all the mixed numbers and make them improper fractions. Step 2. Find one numerator and one denominator with a common factor. Step 3. Divide these numbers by their common factor. Step 4. Repeat the process if there are other numerators and denominators with a common factor. Step 5. Multiply across.
