Skill: fraction-equivalence
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.
