How to Use the Fractions Calculator
Enter two fractions (supports mixed numbers like 1½). Choose operation: +, −, ×, ÷, Simplify, or Compare. See the step-by-step solution.
Fractions Calculator Formula
a/b + c/d = (ad+bc)/bd → simplify with GCD; a/b ÷ c/d = ad/bcGCD= Greatest Common Divisor (Euclidean algorithm)
Example Calculation
3/4 + 2/3:
LCD = 12; 9/12 + 8/12 = 17/12
17/12 = 1 5/12
Frequently Asked Questions
How do you add fractions with different denominators?
Find the LCD (Least Common Denominator), convert both fractions to that denominator, then add the numerators. Example: 1/3 + 1/4 → LCD = 12 → 4/12 + 3/12 = 7/12.
