What Is a Fraction Calculator?
A fraction calculator is an online math tool that performs arithmetic operations on fractions. A fraction represents part of a whole and consists of two numbers: a numerator and a denominator.
For example, in the fraction 3/4, the numerator is 3 and the denominator is 4. The denominator must not be zero.
How to Use the Fraction Calculator
- Enter the numerator of the first fraction.
- Enter its denominator.
- Enter the numerator and denominator of the second fraction.
- Choose addition, subtraction, multiplication, or division.
- Click Calculate to see the simplified answer.
For division, the second fraction must not equal zero.
Fraction Calculation Examples
Adding Fractions
Example: 1/2 + 1/3
Find a common denominator:
1/2 = 3/6
1/3 = 2/6
Add the numerators: 3/6 + 2/6 = 5/6.
Subtracting Fractions
Example: 3/4 − 1/4 = 2/4 = 1/2.
Multiplying Fractions
Example: 2/3 × 3/5 = 6/15 = 2/5.
Dividing Fractions
Example: 1/2 ÷ 1/4 = 1/2 × 4/1 = 2.

Why Simplify Fractions?
A simplified fraction expresses the same value using the smallest possible whole-number numerator and denominator. For example, 6/8 simplifies to 3/4 because both 6 and 8 can be divided by 2.
Simplifying fractions makes answers easier to read, compare, and use in further calculations.
Frequently Asked Questions
How do you add fractions with different denominators?
Convert both fractions to equivalent fractions with a common denominator. Add their numerators and simplify the result.
How do you multiply fractions?
Multiply the numerators together and multiply the denominators together. Then simplify the resulting fraction.
How do you divide fractions?
Multiply the first fraction by the reciprocal of the second fraction. Division by zero is undefined.
Can a fraction have a negative numerator?
Yes. A negative numerator represents a negative fraction when the denominator is positive. A negative denominator can also be normalized by moving the negative sign to the numerator.
Can the result be a whole number?
Yes. For example, 6/3 simplifies to 2.
