FAQ

What can I enter?

Each side accepts a fraction like 3/4, a whole number like 5, or a mixed number like 2 1/3. Put a minus sign in front for negative values, then choose add, subtract, multiply or divide.

What forms is the answer shown in?

You get the simplified fraction, the same value as a mixed number, its improper fraction and the decimal. Repeating decimals are wrapped in parentheses, so 1/3 shows as 0.(3).

Are the results exact?

Yes. Every step uses whole-number math on the numerators and denominators, so nothing is rounded off. Only a repeating decimal with an extremely long cycle is shortened, and only in the decimal row.
