The common denominator of any two or more whole numbers, such as 3, 7 and 9, 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.
7/9-2/3=7/9-6/9=1/9 remember to use the least common denominator.
A common denominator, though not the least, is 63000.

9 is the common denominator. 2/3 = 6/9.
To determine if 3/7 is greater than 4/9, we need to find a common denominator. The least common multiple of 7 and 9 is 63. Converting 3/7 to have a denominator of 63 gives us 27/63, and converting 4/9 to have a denominator of 63 gives us 28/63. Comparing these fractions, we see that 28/63 (4/9) is indeed greater than 27/63 (3/7).
