Fraction Calculator

How to Use Fraction Calculator

1. Enter the numerators and denominators for two fractions; optionally add whole numbers for mixed fractions (e.g., 2 1/2).
2. Select the operation — addition, subtraction, multiplication, or division — from the dropdown.
3. Click Calculate to see the simplified result as a fraction, a mixed number, and a decimal.
4. Read the step‑by‑step working shown below the result — it explains the common denominator method or cross‑multiplication used.

Benefits of Fraction Calculator

• Handles mixed numbers natively — no need to manually convert to improper fractions before entering.
• Automatically reduces results using the GCD (greatest common divisor), ensuring answers are in simplest form every time.
• Displays three output formats — fraction, mixed number, and decimal — so you can use whichever your homework or report requires.
• Step‑by‑step working builds understanding; you see exactly how the common denominator is found and how simplification works.

Frequently Asked Questions

How do I enter a negative fraction?

Put the minus sign in the numerator field. The tool handles negative fractions and normalises the sign so the denominator stays positive.

Can I multiply or divide mixed numbers?

Yes, enter the whole part in the optional “Whole” field. The tool internally converts everything to an improper fraction before applying the operation.

What if I try to divide by zero in the denominator?

The tool will show an alert and refuse to calculate — division by zero is undefined and must be avoided.

Is Fraction Calculator free and private?

Yes — it is 100% free, needs no sign-up, and everything runs in your browser; your data never leaves your device.
