How to Solve Fractions
If you’re curious about how our calculator works behind the scenes, here’s a quick guide to the four basic fraction operations.
1. Adding and Subtracting Fractions
Before adding or subtracting fractions, both fractions must have the same denominator.
Our calculator automatically:
- Finds the Least Common Multiple (LCM)
- Converts both fractions to a common denominator
- Adds or subtracts the numerators
- Simplifies the final answer
Formula
a/b + c/d = (ad + bc) / bd
2. Multiplying Fractions
Multiplication is straightforward.
Simply:
- Multiply the numerators
- Multiply the denominators
- Simplify the result
Formula
a/b × c/d = (ac) / (bd)
3. Dividing Fractions
Division follows the popular “Keep, Change, Flip” method.
- Keep the first fraction.
- Change ÷ into ×.
- Flip the second fraction (take its reciprocal).
- Multiply normally.
- Simplify the result.
Formula
a/b ÷ c/d = a/b × d/c
Common Uses for a Fraction Calculator
Our calculator isn’t only for classrooms.
People use it every day for:

Wherever fractions appear, our calculator helps you solve them faster.
To make your calculations even easier:
- Leave the whole number field empty (or enter 0) if you’re working with regular fractions.
- Double-check that you’ve selected the correct operator (+, −, ×, or ÷).
- Use the Reset Calculator button whenever you want to start a new calculation.
- Bookmark this page so you always have a fast and reliable fraction calculator whenever you need it.
Yes.
Simply enter a minus sign before the whole number or numerator, and our calculator will handle the calculation correctly.
Multiply the whole number by the denominator, then add the numerator.
Keep the original denominator.
Example:
3¼
= (3 × 4 + 1) / 4
= 13/4
Don’t worry—our calculator performs this automatically.
A mixed number combines a whole number with a proper fraction.
For example:
1½
means one whole plus one-half.
Our calculator automatically converts mixed numbers before performing calculations.
A fraction represents division.
Since division by zero is mathematically impossible, a denominator can never be zero.
If you enter zero as the denominator, the calculator will display an error message.
Absolutely!
