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.

8/9, 5/12, 6/7

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.

these are all prime numbers so if they are denominators, the least common denominator would be their product. 5x7x9x11 = 3465

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........

you can get a common denominator by multiplying the denominators together For example 1/5 plus 1/9 common denominator is 5 x 9 = 45 9/45 + 5/45 = 14/45

8/9, 5/12, 6/7

if you give 3/5 and 2/3 common denominators then they are 9/15 and 10/15 respectively. so, no.

You can check this by getting common numerators or denominators for the two fractions. Common numerators: The numerators are 3 and 5. These can be multiplied together to get 15, the new numerator. To get the numerator to equal 15, 3/2 is multiplied by 5/5 to become 15/10. To get the numerator to equal 15, 5/3 is multiplied by 3/3 to become 15/9. 15/9 does not equal 15/10. Common denominators: The denominators are 2 and 3. These can be multiplied together to get 6, the new denominator. To get the denominator to equal 6, 3/2 is multiplied by 3/3 to become 9/6. To get the denominator to equal 6, 5/3 is multiplied by 2/2 to become 10/6. 9/6 doesn't equal 10/6. Both methods show that 3/2 does not equal 5/3.

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

To solve 9/15 - 1/5 we need to get the denominators the same. We can see that 15 can be made from both denominators. 9/15 - 1/5 (3) 9/15 - 3/15 = 6/15 which simplifies to 2/5

these are denominators that are the same for two different fractions. Example 2/3 and 3/4 2/3 = 8/12 3/4 = 9/12 8/12 and 9/12 have the same denominator: 12

There is none because the Least Common Denominator (or LCD) refers to the Least Common Multiple (LCM) of the denominators of two or more fractions or mixed numbers. Even if you converted your whole numbers (x) to their fraction equivalents (x/1), the LCD would always be 1.

The common factors of the denominators are 1 and 3, which won't help you. The least common denominator is 54, which will.

The common denominator of 3 & 9 is 9,as because-3*1=33*2=63*3= 9&.....9*1= 9So here the 9 matches first.

The least common denominator of 9 and 15 (if they are denominators) is the least common multiple of those numbers. We denote this the LCD. One way to find that is write the prime factorization of the two numbers. 9 = 3^2 15 = 3 x 5 Take 3^2 x 5 = 9 x 5 or 45 is the LCM of 9 and 15. This is the product of the primes with the largest exponents. So the LCD or least common denominator is the LCM of 9 and 15 and this is 45.
