# Fraction rules

## Multiplying and Dividing Fractions:

1. Common denominators are NOT needed.
2. Always change mixed numbers to improper fractions.
3. CANCEL (reduce) between any numerator and any denominator if you can, but cancel only when a multiplication sign is present: Never cancel when you have a division sign.
4. TO MULTIPLY: Multiply numerator times numerator, denominator times denominator. Reduce answer to a mixed number in lowest terms.
5. TO DIVIDE: Change the divide sign to a multiplication sign, then invert the second fraction and multiply as in Step 4.
