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?
Yes — see the Fraction to Decimal Calculator.
