Fractions can be tricky — especially when you’re adding unlike denominators, dividing by a fraction, or trying to simplify a messy result. This Fraction Calculator handles all four operations cleanly and instantly, automatically simplifies the answer using the GCD, and walks you through every single step so you always know exactly what happened and why.
What Operations Can You Perform?
This calculator covers everything you’d need when working with fractions:
- Addition — finds the LCD, rewrites both fractions, then adds the numerators
- Subtraction — same LCD process, but subtracts the numerators instead
- Multiplication — multiplies numerators together and denominators together directly
- Division — flips the second fraction and multiplies by its reciprocal
- Automatic simplification — reduces every result to its simplest form by dividing through the GCD
- Mixed number conversion — converts improper fractions into mixed numbers where applicable
