|---|---|---|
| Addition | a/b + c/d = (ad + bc) / bd, then simplify | 1/2 + 1/3 = 5/6 |
| Subtraction | a/b − c/d = (ad − bc) / bd, then simplify | 3/4 − 1/4 = 1/2 |
| Multiplication | a/b × c/d = ac / bd, then simplify | 2/3 × 3/4 = 1/2 |
| Division | a/b ÷ c/d = a/b × d/c, then simplify | 1/2 ÷ 1/4 = 2 |
