Frequently Asked Questions

How do I add fractions?

Find a common denominator, convert both fractions, then add the numerators. For example: 1/2 + 1/3 = 3/6 + 2/6 = 5/6.

Does this simplify fractions automatically?

Yes — all results are automatically reduced to lowest terms using the Greatest Common Divisor (GCD). Mixed numbers are shown when the result is improper.

Can I enter whole numbers?

Absolutely. Just type the whole number without a denominator — the calculator treats it as a fraction over 1.
