Frequently asked questions

How do you simplify a fraction?

Find the greatest common factor (GCF) of the numerator and denominator, then divide both by it.

What does it mean for a fraction to be in "lowest terms"?

It means the numerator and denominator share no common factor other than 1 — the fraction can't be reduced any further.

I need the decimal equivalent too — is there a calculator for that?
