That is '9 x 13' = 117

Answer 2

The common denominator for 9 and 13 is the product of the two numbers, which is 9 * 13 = 117. In fractions, the denominator represents the total number of equal parts into which a whole is divided. When adding or subtracting fractions, it is necessary to have a common denominator to combine the fractions accurately.

Answer 3

The common denominator of any two or more whole numbers, such as 9 and 13, 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.
