The common denominator of any two or more whole numbers, such as 13 and 12, 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 is the common denominator for 12 and 13?

There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions.

What is the Greatest Common Denominator of 6 and 13?

The greatest common denominator of any set of denominators is infinite.


How do you minus fractions?

First, you have to have a lowest common denominator. Eg: 1/2 - 6/13 The lowest common denominator is 26, because 13 * 2 is 26. You multiply 1/2 by 13, to make the denominator 26, which equals 13/26, then multiply 6/13 by 2 to get 12/26. So the equation with the lowest common denominators now plugged in is: 13/26 - 12/26 Subtract the numerators (13 and 12), so the answer is 1/26.


What are the common denominators of 13 and 7?

The common denominator of any two or more whole numbers will always be 1.

There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions.


What is the decimal fraction between 1.2 and 1.5 and show me how you get the answer?

13/10. 1.2 = 12/10. 1.5 = 15/10. The denominators are the same and 13 is between 12 and 15 so 13/10 is a valid answer.

What is one third plus three fourths?

To work this problem, you have to change the fractions to a common denominator. In this case, the common denominator is 12. 1/3 = 4/12 3/4 = 9/12 4/12 + 9/12 = 13/12 = 1 1/12
