Add, subtract, multiply, and divide fractions — step by step
Chain +, −, × and ÷ on fractions, whole and mixed numbers; every answer comes simplified as a fraction, mixed number, decimal and percent.
Decimal → fraction
Exact decimals only — 0.375 becomes 3/8. For repeating ones like 0.333…, divide instead: 1 ÷ 3.

Using the tool
Start with a fraction or whole number, then keep going: apply +, −, ×, or ÷ to the running result, as many steps as you like. Whole and mixed numbers welcome (use the left box for the whole part). Each answer is simplified and shown as a fraction, a mixed number, a decimal, and a percent — and the decimal → fraction box converts the other way (0.375 = 3/8).
The math
Each operation applies to the running result, left to right (so 1/2 + 1/4 × 2 is (1/2 + 1/4) × 2). Adding and subtracting use a common denominator; multiplying goes straight across; dividing flips the operand and multiplies. Every result is reduced by its greatest common divisor, then shown as a mixed number, a decimal, and a percent.
