❓ Frequently asked questions
How do I add two fractions?
Enter the two fractions and choose Add — the calculator finds a common denominator, adds the numerators, and reduces the answer to simplest form automatically.
Can I work with mixed numbers?
Yes. Mixed numbers like 2 1/3 are converted to improper fractions before the calculation, and the result can be shown as a mixed number or a decimal.
Does the fraction calculator simplify answers?
Always. Every result is reduced to its simplest form, for example 4/8 becomes 1/2.
