What this calculator does
Convert a percentage to a simplified fraction and decimal.
How it works
The calculator evaluates fraction = percent ÷ 100, then reduce numerator and denominator by their greatest common divisor. Inputs are checked before calculation, and invalid values such as zero denominators or out-of-range selections produce a clear error instead of a misleading result.
