How do I use the Fraction Calculator?

Enter the first fraction by typing the numerator and denominator. Optionally add a whole number for mixed numbers like 2 ½. Choose the operation: addition (+), subtraction (−), multiplication (×), or division (÷). Enter the second fraction the same way. You can mix fractions and mixed numbers freely. Click Calculate to see the result as a simplified fraction, mixed number, and decimal. Step-by-step work is shown below. Use the Simplify button to reduce a single fraction to its lowest terms without performing an operation.

Is the Fraction Calculator free?

Yes, the Fraction Calculator is completely free. It runs entirely in your browser with no signup, no download, and no data sent to any server.

How to calculate with fractions

1 Enter the first fraction by typing the numerator and denominator. Optionally add a whole number for mixed numbers like 2 ½.
2 Choose the operation: addition (+), subtraction (−), multiplication (×), or division (÷).
3 Enter the second fraction the same way. You can mix fractions and mixed numbers freely.
4 Click Calculate to see the result as a simplified fraction, mixed number, and decimal. Step-by-step work is shown below.
5 Use the Simplify button to reduce a single fraction to its lowest terms without performing an operation.

Working with fractions requires finding common denominators for addition and subtraction, cross-multiplying for multiplication, and flipping the second fraction for division. This calculator handles all of these operations automatically and shows you each step so you can follow the math. Every result is automatically simplified to lowest terms using the greatest common divisor.

The step-by-step display shows the complete solution process. For addition and subtraction, it finds the least common denominator, converts both fractions, then combines. For multiplication, it multiplies numerators and denominators separately. For division, it flips the second fraction and multiplies. The final step shows the GCD used to simplify the result.

Mixed numbers are supported on both sides of the equation. Enter the whole number, numerator, and denominator separately. The calculator converts mixed numbers to improper fractions internally, performs the operation, and converts back to a mixed number in the result. Results are displayed in three formats: improper fraction, mixed number, and decimal.
