Frequently asked questions

How do I simplify a fraction?

Type it as numerator/denominator, for example 18/24, and the calculator divides both by their greatest common divisor to give the lowest terms (3/4 in that case), along with the decimal, mixed-number and percent forms.

Can it convert a decimal to a fraction?

Yes. Type a decimal like 0.75 in the decimal field and it returns the exact simplified fraction (3/4) when the decimal terminates.

What is a mixed number?

It splits an improper fraction into a whole part plus a proper fraction, for example 7/4 becomes 1 3/4.
