How to Calculate Fractions

Fractions represent parts of a whole and are fundamental to mathematics. This calculator performs addition, subtraction, multiplication, and division of fractions, automatically simplifying the result to its lowest terms.

Fraction Operations

• Addition/Subtraction: Find a common denominator, then add or subtract the numerators. a/b + c/d = (ad + bc) / bd
• Multiplication: Multiply numerators together and denominators together. a/b × c/d = ac / bd
• Division: Multiply by the reciprocal. a/b ÷ c/d = a/b × d/c = ad / bc

Results are automatically simplified using the Greatest Common Divisor (GCD) to find the lowest terms.
