Fraction Calculator

Free Fraction Calculator. Add, subtract, multiply, and divide fractions, mixed numbers, and improper fractions with step-by-step solutions and decimal conversion.

Tool Overview & Core Functionality

Performs exact fraction arithmetic, mixed number conversions, least common multiple (LCM) denominators, and step-by-step rational reduction.

              Rational Number Arithmetic & Greatest Common Divisor Simplification:
            
              a/b +- c/d = (ad +- bc)/bd | GCD Reduction via Euclidean Algorithm

This calculator executes instantaneous, zero-latency computations strictly client-side. No financial balance, health metric, or personal chronological details are transmitted to external servers.

Admin Practical Note: Mixed Number Arithmetic Pitfalls

Proper vs Improper Fraction Processing Order

Converting 3 1/4 * 2 1/2: Must convert to improper fractions (13/4 * 5/2 = 65/8) before cross-simplifying

Admin Practical Takeaway: Never perform multiplication or division directly on whole numbers and fractions separately; always transform to pure improper ratios first.
