How it works

Addition/subtraction: find LCD, convert fractions, combine numerators. Multiplication: multiply numerators and denominators directly, then simplify. Division: multiply by the reciprocal of the divisor. Always simplify by dividing by the GCF. Mixed numbers convert to improper fractions first: a b/c = (a×c + b)/c. Results are given in simplest form with step-by-step detail.
