Addition

a/b + c/d = (ad + bc) / (bd)
Example: 1/2 + 1/3 = (1×3 + 1×2) / (2×3) = 5/6

Subtraction

a/b - c/d = (ad - bc) / (bd)
Example: 1/2 - 1/3 = (1×3 - 1×2) / (2×3) = 1/6

Multiplication

a/b × c/d = (ac) / (bd)
Example: 1/2 × 1/3 = (1×1) / (2×3) = 1/6

Division

a/b ÷ c/d = (ad) / (bc)
Example: 1/2 ÷ 1/3 = (1×3) / (2×1) = 3/2 = 1½
