Equivalent Fractions Calculator

Three tools in one: simplify any fraction to lowest terms, build an equivalent fraction with the denominator or numerator you choose, or test two fractions for equivalence with cross-products. Every answer comes with the full working shown step by step.

Simplify to lowest terms

Enter a fraction. The calculator divides top and bottom by their GCF.

    Build an equivalent fraction

    Enter a fraction and the denominator or numerator you want. The target must be a multiple.

      Are two fractions equivalent?

      Enter both fractions. Cross-products decide — no guessing.
