Add, subtract, multiply, or divide two fractions and simplify the result.
Add / subtract: a/b ± c/d = (a·d ± c·b) / (b·d), then divide numerator and denominator by their GCD to simplify. Example: 3/4 − 2/3 = (9 − 8)/12 = 1/12. Multiply: (a/b)·(c/d) = (a·c)/(b·d). Divide: (a/b) ÷ (c/d) = (a·d)/(b·c) — flip the second fraction and multiply.
The tool accepts negatives and improper fractions (like 7/4) and always returns the fully reduced form plus a decimal, so you can plug it straight into a recipe (¾ cup + ⅔ cup = 17/12 ≈ 1.42 cups) or a cut list for woodworking without hunting for a calculator app.
Great for recipes, sewing patterns, timber cut lists, and helping kids check homework without introducing rounding errors.
