Fraction Math & Operations Calculator. Add, subtract, multiply, and divide fractions and mixed numbers with step-by-step simplification and common denominators. ZechKit provides this tool completely free and online, optimized for instant, accurate computations directly inside your web browser.
A Fraction Calculator performs arithmetic operations—addition, subtraction, multiplication, and division—on proper fractions, improper fractions, and mixed numbers.
Operational Rules: Addition & Subtraction: Find the Least Common Denominator (LCD), convert numerators, perform addition/subtraction, and simplify. Multiplication: (a/b) × (c/d) = (a×c) / (b×d). Division: Multiply by the reciprocal: (a/b) ÷ (c/d) = (a/b) × (d/c) = (a×d) / (b×c).
Mixed Numbers to Improper Fractions: Convert mixed numbers using: a b/c = (a × c + b) / c.
Simplification: Final fraction results are reduced to lowest terms by dividing numerator and denominator by their Greatest Common Divisor (GCD).
