If you mean the steps, they are as follows:* Identify a common denominator. Any common denominator will do.
* Convert both fractions to equivalent fractions, with the common denominator found in the previous step. (If the fractions start off with the same denominator, there is nothing else to do in these first two steps.)
* Add the numerators. That's the numerator of the result. Copy the common denominator as the denominator of the result.
* Check whether you can simplify the resulting fraction.
