Add, subtract, multiply or divide any two fractions, including mixed numbers, and watch the working unfold: common denominators, keep flip change, simplifying with the highest common factor, and converting top-heavy answers back to mixed numbers. Each answer stays exact, as a fraction, rather than turning into a rounded decimal.

    Worked Example

    Work out 12 + 14.

    1. The lowest common denominator of 2 and 4 is 4
    2. Rewrite both fractions over 4:12 = 24, and 14 stays as it is
    3. Add the numerators:2 + 1 = 3, so the answer is 34, which is already in simplest form
