What it does
Add, subtract, multiply, and divide two fractions. Enter numerators and denominators, pick an operation, and the calculator returns the result as a reduced fraction, a mixed number, and a decimal. All math runs in the browser using GCD-based reduction, so results are exact rational numbers, not floating-point approximations.
Great for cooking (half of ¾ cup), carpentry (feet-and-inches math), probability puzzles, and homework. For decimal-to-percent conversions see percentage calculator; for proportions use the ratio calculator.
