What is the Fraction Calculator?
A fraction shows part of a whole as one whole number over another. Working with fractions means finding common denominators, multiplying across, flipping to divide and simplifying at the end — easy to get wrong by hand. This calculator does all of it and shows every step.
Enter two fractions (or mixed numbers), choose add, subtract, multiply or divide, and get the answer as a simplified fraction, a mixed number and a decimal, along with the working. Negative fractions are supported, and a simplify mode reduces any single fraction to lowest terms.
