In the above problem, the denominators are already the same. If they are not, a common denominator must be found. For instance, before adding 1/3 cup to 1/2 cup, it is necessary to find a denominator that is divisible by both two and three. The denominator in this case is six. To make 1/3 into a fraction with a denominator of six, both numbers are multiplied by two, and to make 1/2 into a fraction with a denominator of six, both numbers are multiplied by three. The problem becomes 2/6 cup plus 3/6 cup equals 5/6 cup.
