How to use the Fraction Calculator

Working with fractions requires finding common denominators or reciprocating for division. This tool simplifies that entire process. To start, enter the **Numerator** (top number) and **Denominator** (bottom number) for both fractions. Select your desired operation: **Addition (+)**, **Subtraction (−)**, **Multiplication (×)**, or **Division (÷)**. When you click **"Calculate & Simplify"**, the tool performs the arithmetic and automatically reduces the resulting fraction to its simplest form using the Greatest Common Divisor (GCD). It also provides a decimal equivalent for your convenience, making it perfect for verifying homework or complex math problems.

  • Auto-Simplification: Always gives the result in the lowest possible terms.
  • All Operations: Handles all four basic math functions.
  • Decimal Conversion: Shows you the decimal value alongside the fraction.
What is a 'Simplified' fraction? +
A simplified or reduced fraction is one where the numerator and denominator have no common factors other than 1. For example, 4/8 simplifies to 1/2.
Can I use zero as a denominator? +
No, division by zero is undefined in mathematics. The denominator must always be a non-zero number for the fraction to be valid.
