1. Simplify the fractions

Simplify the fractions the same way you do when multiplying regular fractions. Use cancelling, common denominators and common factors between the top and bottom rows to get a simplified equation.

2. Multiply the numbers and expressions across the top rows

Write the answer on the top row.

3. Multiply the numbers and expressions across the bottom rows

Write the answer on the bottom row.

4. Simplify again if necessary

Check the final answer to ensure it can't be reduced any further.
