How fractions are calculated
To add or subtract fractions, denominators are matched using the least common multiple. To multiply, numerators and denominators are multiplied together, and to divide, you multiply by the inverse fraction. The result is simplified by dividing by the greatest common divisor.
a/b + c/d = (a×d + c×b) / (b×d)
Worked example
1/2 + 1/3 = (1×3 + 1×2) / (2×3) = 5/6.
