The common denominator of any two or more whole numbers, such as 3 5 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.

What common denominators of 3 and 5 and 7 and 9?
Only 1.
Least common denominators?
8/9, 5/12, 6/7
What is a explanation for the least common denominator for 3 and 12?
if you mean for 1/3 and 1/12, then to find common denominators, you just list multiples of the denominators 3 and 12. for 3 :3, 6, 9, 12... for 12:12, 24, 36... 12 is the smallest number in both lists, so it is the least common denominator.
What is the common denominator for 5 7 9 11?
these are all prime numbers so if they are denominators, the least common denominator would be their product. 5x7x9x11 = 3465
What is 2 over 5 plus 1 over 9?
2/5 + 1/9 (multiply opposite numerators by opposite denominators and the denominators by each other to get the fractions into a common form) = (2 x 9)/(5 x 9) + (5 x 1)/(5 x 9) complete the multiplications = 18/45 + 5/45 add the two fractions = 23/45 which cannot be reduced further........
