Última actualización: July 2026
A fraction calculator adds, subtracts, multiplies or divides two fractions or mixed numbers using exact integer arithmetic, then simplifies the result with the greatest common divisor. You get the answer as a reduced fraction, a mixed number and a decimal, plus the working shown step by step — all instantly in your browser.
Cómo usar Fraction Calculator
- Enter both fractions (add a whole part for mixed numbers).
- Choose + − × or ÷.
- Read the simplified fraction, mixed number, decimal and the worked steps.
Preguntas frecuentes
Does it simplify the result?
Yes — the answer is always reduced to lowest terms using the greatest common divisor, and shown as a mixed number when it's improper.
Can I use mixed numbers like 1 2/3?
Yes. Each side has an optional whole-number field; the calculator converts to an improper fraction before computing.
Is anything I enter stored?
No. All the arithmetic happens in your browser — your numbers never leave your device.
