Adding, Subtracting, Multiplying, and Dividing Fractions

To add or subtract fractions, first convert both to a common denominator, then add or subtract the numerators and simplify the result. Fraction multiplication is simpler: multiply the numerators together and the denominators together, then reduce. For example, 1/2 × 3/4 = 3/8.

To divide, multiply the first fraction by the reciprocal of the second — flip the second fraction upside down and multiply. So 3/4 ÷ 1/2 becomes 3/4 × 2/1 = 6/4 = 3/2. This fractions calculator can be used as a dividing fractions calculator for exactly this kind of problem, and it also handles negative fractions in both the numerator and denominator, reducing the result to lowest terms.

Every operation shows the simplified answer, the equivalent mixed number when applicable, and the step-by-step working, making it a handy negative fraction calculator and a study aid for fraction homework.
