Add, subtract, multiply or divide exact fractions and mixed numbers without rounding the answer.
Calculated outcomes
- Decimal Approximation
- 0.833333333333
Assumptions and estimates
- Exact rational arithmetic for bounded integer, fraction and mixed-number inputs. Decimal result is a floating-point approximation; exact fraction is authoritative.
- Method: Use integer rational arithmetic, normalise denominator signs and reduce by the greatest common divisor. Mixed numbers accept a space, such as −1 1/2.
- Bounded integer/fraction inputs, up to 18 digits per part. Denominators cannot be zero; decimal approximation is not the exact result. No expression execution.
