What this calculator does

Divide one fraction by another and reduce the result to lowest terms.

How it works

The calculator evaluates (a/b) ÷ (c/d) = ad ÷ bc. 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.

Input query strings and outputs
