Type a fraction like 7/12, or a decimal like 0.75 — fracgo converts both ways, rounds to your chosen precision, and reduces every fraction to its simplest form with the working shown.
The digit above the line is the numerator; the one below is the denominator. Denominator cannot be zero.
Enter any number with a decimal point, like 0.75, 3.25 or -1.6.

Fracgo converts any fraction — proper, improper, or mixed — into its exact decimal equivalent. Students checking homework, machinists reading blueprints, and cooks scaling recipes all run into fractions that are easier to work with as decimals. Type something like 7/8 or 3 11/16 and you get 0.875 or 3.6875 without reaching for a calculator or doing long division by hand. The tool handles repeating decimals too, so 1/3 gives you 0.333... rather than a rounded value that quietly breaks downstream calculations.
Enter the numerator and denominator and the decimal appears instantly, calculated to the precision you choose.
Yes. Decimal-to-fraction conversion also simplifies the result automatically, so 0.75 comes back as 3/4.
Yes. The long-division and greatest-common-divisor steps are displayed so you can follow exactly how the answer was reached.
It is free, requires no sign-up, and every calculation runs locally in your browser.
Each fraction gets its exact decimal, the long division that produced it and whether the digits stop or repeat — the single fact that decides if a written decimal is the real value.
