Represent → compare → factor → verify

Equivalent fraction forms should preserve the same rational value, and number-theory relationships should agree across factors, remainders, GCF, multiples, and prime structure. Use the connected tools to verify rather than relying on an isolated answer.

Exact fraction relationships and repeating output

Fractions represent exact ratios as long as the denominator is nonzero. Decimal and percent forms may terminate or repeat indefinitely, so a displayed decimal can be a rounded representation even when the underlying fraction is exact. Percent simply scales the same ratio by 100; it does not change the proportional relationship.

Verify with the inverse operation

Reduce numerator and denominator by their greatest common factor, or convert the displayed result back to the original form. For repeating decimals, keep the exact fraction when downstream precision matters instead of copying a short rounded decimal. Negative signs can be placed on the numerator, denominator, or whole ratio but should be normalized consistently. Financial, measurement, and statistical contexts may also impose their own rounding rules after the mathematical conversion.
