About This Calculator

This calculator adds two fractions, whether they are proper, improper, or mixed numbers. It supports negative values and different denominators. The result is automatically simplified and shown in both improper and mixed number formats, with detailed calculation steps included.

How It Works

  1. Enter the integer, numerator, and denominator for both fractions.
  2. The calculator converts mixed numbers to improper fractions if needed.
  3. It finds the least common denominator (LCD) of both fractions.
  4. The fractions are adjusted to have the same denominator, then added together.
  5. The result is simplified and shown in multiple formats with step-by-step explanations.

Frequently Asked Questions

How do you add two fractions?

Find a common denominator, convert both fractions, add the numerators, and simplify the result. For example: 1/3 + 1/6 = 1/2.

Can I add mixed numbers like 1 1/2 and 2 2/3?

Yes. The calculator converts them to improper fractions before adding and simplifies the final result back to a mixed number.

What if the denominators are different?

The calculator finds the least common denominator (LCD) so you don't have to.

Will the result always be simplified?

Yes. The final answer is always reduced to its simplest form, whether it's a proper, improper, or mixed number.

Does it work with negative fractions?

Yes. You can add negative fractions like -1/2 + 3/4 and get accurate results.
