The common denominator of any two or more whole numbers, such as 8 9 and 10, will always be one (1) because 'common denominator' refers to the denominators of two or more fractions or mixed numbers, not whole numbers. So, a set of whole numbers (x,x) would have to be converted to their fraction equivalents, i.e., x/1, which will always yield a denominator of 1.

How do you rewrite each pair of fraction with a common denominator?
For Example if the problem is 3/8 + 9/10 = ? First you would find the least common multiple of each denominator. In this case it would be 80. And you would multiply the denominator and the numerator with the number that equals 80, but you don't have to have the numerator the same answer. So: 3/8 X 10/10 = 30/80 Then you do the other side: 9/10 X 8/8 = 72/80 Now you would just work out the problem: 30/80 + 72/80 = 102/80 Then you would divide the numerator and denominator: 102/80 = 1 11/40
