Our fraction calculator performs all four arithmetic operations on fractions and mixed numbers, showing the step-by-step working so you can understand the method, not just the answer. To add or subtract fractions, we find a common denominator. To multiply, we multiply numerators and denominators. To divide, we multiply by the reciprocal. All results are simplified to their lowest terms. The calculator also handles mixed numbers (like 1½) and improper fractions (like 3/2), converting between the two forms as needed.
