What is Fractions?
Fraction arithmetic is exact: adding needs a common denominator, multiplying just goes across, and dividing flips the second fraction. This calculator works through whichever applies.
How it works
We parse both fractions, find the least common denominator for + and −, operate on the numerators, then reduce with the greatest common factor — showing each step and rendering the inputs and answer as fraction bars.
