About This Free Online Fraction Calculator
Our free fraction calculator adds, subtracts, multiplies, and divides fractions and mixed numbers, then shows the answer fully reduced to its simplest form. Enter two fractions, choose an operation, and the tool finds a common denominator where needed, performs the math, and converts improper results back into a clean mixed number. It is built for homework, baking and recipe scaling, woodworking and construction measurements, and any everyday situation where you need an exact answer instead of a rounded decimal. Because it simplifies automatically, you avoid the tedious step of finding the greatest common divisor by hand, and you can check your own work in seconds. The calculator runs entirely in your browser with instant results, no signup, and no ads getting in the way of the answer you came for.
