A comprehensive tool to handle all your fraction needs. Simplify complex fractions to their lowest terms, convert them to exact decimals and percentages, or perform arithmetic operations between two fractions instantly.
How to use the Fraction Calculator?
- Convert & Simplify: Enter a numerator (top number) and a denominator (bottom number). The calculator will simplify the fraction using the Greatest Common Divisor (GCD) and output the exact decimal and percentage equivalents.
- Fraction Math (+ − × ÷): Enter two distinct fractions and select the mathematical operation. The tool will calculate the exact resulting fraction (simplified) and decimal format.
Fraction Math Formulas
Frequently Asked Questions
Find the Greatest Common Divisor (GCD) of both the numerator and the denominator, and then divide both by that number. For instance, for 15/20, the GCD is 5. Dividing both by 5 yields 3/4.
You must first find a common denominator by multiplying the denominators together (or finding the Least Common Multiple). Then adjust the numerators accordingly before adding them together.
Simply divide the top number (numerator) by the bottom number (denominator) using a calculator.
To divide fractions, multiply the first fraction by the reciprocal (flipped version) of the second fraction.
Yes, if the numerator is larger than the denominator (e.g., 9/4), the calculator handles the math and simplification perfectly.
Division by zero is mathematically undefined. The calculator will throw an error if you attempt to use 0 as a denominator.
