What Is a Fraction Calculator?
A fraction calculator is a free online tool that helps you add, subtract, multiply, and divide fractions instantly. It also simplifies fractions, converts them to decimals, and shows every step so you can learn how the answer is found.
What Is a Fraction?
A fraction is simply a way of showing a part of a whole. It consists of two essential parts:
Shows how many equal parts you currently have.
Shows how many equal parts the whole is divided into.

4 Basic Fraction Operations
Add Fractions Calculator
Addition (+)Requires a common denominator. If they differ, the calculator finds the Least Common Denominator (LCD) first before adding numerators.
Example: 1/4 + 1/6 (LCD = 12)
3/12 + 2/12 = 5/12
Subtract Fractions Calculator
Subtraction (−)Works similarly to addition—match the denominators using the LCD first, then subtract the top numerators.
Example: 3/4 − 1/3 (LCD = 12)
9/12 − 4/12 = 5/12
Multiply Fractions Calculator
Multiplication (×)No common denominator needed. Simply multiply top numbers together, bottom numbers together, and reduce to simplest form.
Example: 2/3 × 3/5 = 6/15
Simplified = 2/5
Divide Fractions Calculator
Division (÷)Flip (find the reciprocal of) the second fraction, then multiply straight across as usual.
Example: 1/2 ÷ 3/4 = 1/2 × 4/3 = 4/6
Simplified = 2/3
Simplify Fractions
A fraction is in its simplest form when the numerator and denominator share no common factor other than 1. This calculator automatically reduces every answer to lowest terms, so you never have to simplify manually.
Mixed Numbers & Improper Fractions
A mixed number combines a whole number and a fraction (e.g., 2 ¾). An improper fraction has a top number larger than the bottom (e.g., 11/4). They share the exact same value—enter either format and our tool handles conversions seamlessly.
Real-Life Examples of Fraction Math
A recipe makes 6 servings and calls for 2/3 cup of sugar. You only want 3 servings (half the recipe).
Fraction multiplication allows quick scaling of cooking ingredients up or down.
A piece of wood is 3/4 inch thick, and you stack two of them together to check total thickness.
Carpenters and DIYers rely on quick fraction checks for precise inch measurements.
