Frequently asked questions
How do you add fractions with different denominators?
Put them over a common denominator, add the numerators, then reduce. For example 1/2 + 1/3 = 3/6 + 2/6 = 5/6. The calculator handles the common denominator for you.
Does it simplify the answer?
Yes — every result is reduced to lowest terms using the greatest common divisor, and shown as a mixed number when it's larger than 1.
