Quick Reference: Fraction Operations
| Operation | Rule | Example | Key Point |
|---|---|---|---|
| Add (same denom) | Add numerators only | 2/7 + 3/7 = 5/7 | Keep denominator same |
| Add (diff denom) | Find LCM first | 1/3 + 1/4 = 4/12 + 3/12 = 7/12 | Convert to same denominator |
| Multiply | Top × top, bottom × bottom | 2/3 × 3/4 = 6/12 = 1/2 | Simplify after |
| Divide | Keep, Flip, Change (KFC) | 2/3 ÷ 3/4 = 2/3 × 4/3 = 8/9 | Flip second fraction |
