Frequently Asked Questions
How do I add two fractions?▾
Convert both fractions to a common denominator (a/b + c/d = (ad + cb)/bd), add the numerators, then reduce the result by dividing numerator and denominator by their greatest common divisor.
What does reduced to lowest terms mean?▾
A fraction is in lowest terms when its numerator and denominator share no common divisor other than 1. This is achieved by dividing both by their GCD.
