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.

Frequently asked questions
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.
