Frequently Asked Questions
How do I add fractions?+
Find a common denominator, add the numerators: a/b + c/d = (ad + bc) / bd. Then simplify. Example: 3/4 + 1/2 = (3×2 + 1×4) / (4×2) = 10/8 = 5/4 = 1¼.
How do I multiply fractions?+
Multiply numerators together and denominators together: a/b × c/d = (a×c) / (b×d). Then simplify. Example: 3/4 × 1/2 = 3/8.
How do I divide fractions?+
Multiply by the reciprocal: a/b ÷ c/d = a/b × d/c = (a×d) / (b×c). Example: 3/4 ÷ 1/2 = 3/4 × 2/1 = 6/4 = 3/2 = 1½.
