Fraction Calculator

Type each fraction as a whole number plus a numerator and denominator (for example 1 2/3), pick plus, minus, multiply, or divide, and click Calculate. You get the answer as a mixed number, an improper fraction, and a decimal, with every step shown.

To simplify fractions, divide the top and bottom by their greatest common divisor — for example 2/4 simplifies to 1/2 because both divide by 2. This fraction calculator simplifies every result automatically and shows the step.

A mixed number combines a whole number with a fraction, like 2 1/3. This mixed number calculator reads your input in mixed-number style and shows the answer that way too, next to the improper fraction 7/3 and the decimal 2.333333.

Convert both to improper fractions, find the least common denominator, rewrite each fraction with it, then add or subtract the numerators. The steps panel walks through exactly that — try 1/2 + 1/3 and watch it find the common denominator 6.

Flip the second fraction (keep, change, flip) and multiply: (1/2) divided by (1/4) = (1/2) x (4/1) = 4/2 = 2. The calculator shows the flipped fraction in its steps.
