About the Fraction Calculator
Enter two fractions and an operation to get the answer reduced to lowest terms, along with its mixed-number and decimal forms. Handles common-denominator arithmetic and simplification for you.
How it’s calculated
Addition/subtraction use a common denominator; multiplication multiplies across; division multiplies by the reciprocal. The result is reduced by its greatest common divisor.
Example calculation
1/2 + 1/3 = 5/6 ≈ 0.833.
