Well, isn't that just a happy little question! To find the common denominator for 12, 7, and 9, we can look for the smallest number that all three can divide evenly into. In this case, the common denominator would be 252, as it is the smallest number that 12, 7, and 9 can all divide into evenly. Remember, there are no mistakes in math, just happy little accidents!

The common denominator of any two or more whole numbers, such as 12 7 and 9, will always be one (1) because common denominators 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.
