Questions Fréquentes
How does this converter work?
It multiplies the decimal by the max denominator, rounds to get an integer numerator, then simplifies the fraction using the Greatest Common Divisor (GCD).
What should I set the max denominator to?
A higher max denominator gives a more precise fraction. Use 1000 for most cases. For repeating decimals like 0.333..., try 3 or 9 as the max denominator.
