Free Fraction Calculator — Add, Subtract, Multiply and Divide with Steps
A fraction shows part of a whole as one whole number over another. Working with fractions means finding common denominators, multiplying across, flipping to divide and simplifying at the end — easy to get wrong by hand. This calculator does all of it and shows every step.
Enter two fractions (or mixed numbers), choose add, subtract, multiply or divide, and get the answer as a simplified fraction, a mixed number and a decimal, along with the working. Negative fractions are supported, and a simplify mode reduces any single fraction to lowest terms.
Key features
All four operations
Add, subtract, multiply and divide fractions and mixed numbers.
Step-by-step working
See the common denominator and simplification steps.
Three answer formats
Simplified fraction, mixed number and decimal.
Simplify mode
Reduce any fraction to lowest terms.
How to use it
- Enter the numerator and denominator (and whole number if it is a mixed number) for each fraction.
- Choose the operation.
- Read the answer and the steps.
- Copy the result.
Worked example
Example
1/2 + 1/3 = 3/6 + 2/6 = 5/6 ≈ 0.8333 3/4 ÷ 5/8 = 3/4 × 8/5 = 24/20 = 6/5 = 1 1/5 = 1.2

Tips for the best results
- Always simplify the final answer to lowest terms.
- To divide, multiply by the reciprocal of the second fraction.
- Convert mixed numbers to improper fractions before calculating.
- Check the decimal to sanity-check the fraction.
Common mistakes to avoid
- Adding numerators and denominators directly (1/2 + 1/3 is not 2/5).
- Forgetting to find a common denominator when adding or subtracting.
- Dividing by a fraction with a zero numerator.
