About Fraction Calculator
Adding fractions requires a common denominator. The tool combines two numerators over the product of their denominators, then divides both by their greatest common divisor to simplify the sum.
Important considerations
This tool adds two fractions only. Numerators must be whole numbers between −1,000,000 and 1,000,000; denominators must be positive whole numbers up to 1,000,000. The decimal result is rounded for display.
