FAQ

Common questions

What is the difference between an improper fraction and a mixed number?

An improper fraction has a numerator that is at least as large as the denominator, while a mixed number shows a whole number plus a fraction part.

Why is a zero denominator not allowed?

A denominator of zero makes the fraction undefined, so the conversion cannot be completed.

Does the calculator also show a decimal equivalent?

Yes. It shows the decimal value of the fraction so you can compare the same number in multiple formats quickly.
