Decimal to Fraction: Reduce Decimals to Lowest Terms
Decimals are handy for calculators and fractions are handy for people. Reducing a decimal shows the simple ratio hiding inside it.

The tool reads the digits after the decimal point to build the starting fraction, then divides numerator and denominator by their GCD.
