How do you find a common denominator?

We can obtain common denominators by multiplying both numerator (top) and denominator (bottom) by the same amount. For example, consider the addition of two fractions that do not have the same denominator: Addition of 2⁄5 and 1⁄2 . First, multiply 2⁄5 by 2⁄2 to get 4⁄10 .
