A straightforward fraction calculator
Add, subtract, multiply, or divide fractions and mixed numbers. Separate whole-number, numerator, and denominator fields are converted to exact integer ratios, combined, and reduced by their greatest common divisor.
Fraction results use exact integer arithmetic rather than floating-point approximations. Inputs are processed in your browser, and changing a value updates the result immediately.
