Free Fraction Calculator Online — Add Subtract Multiply Divide

ToolzNova's free fraction calculator performs all four arithmetic operations on fractions — addition, subtraction, multiplication, and division — plus simplification. Every result is shown in simplified form with the step-by-step working.

Fractions are fundamental in mathematics, cooking, construction, and science. Our calculator handles proper fractions, improper fractions, and shows the steps so you learn how the calculation works.

Fraction Operation Formulas

Adding: (a/b)+(c/d) = (ad+bc)/bd. Subtracting: (a/b)−(c/d) = (ad−bc)/bd. Multiplying: (a/b)×(c/d) = ac/bd. Dividing: (a/b)÷(c/d) = ad/bc. All results are then simplified by dividing by the GCD.
