That depends what you want to do. If you multiply both the numerator and the denominator by the same number, you get another fraction that stands for the same number - an equivalent fraction. For example, if you have the fraction 1/2, you multiply top and bottom by 2, to get 2/4. 2/4 is simply another name for 1/2.
