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........
What common denominators of 3 and 5 and 7 and 9?
Only 1.
How do you add fractions if the denominators are not in the same times table?
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
Least common denominators?
8/9, 5/12, 6/7
Is three fifths equivalent to two thirds?
if you give 3/5 and 2/3 common denominators then they are 9/15 and 10/15 respectively. so, no.
What is the lowest common multiple of 4 5 and 9?
The greatest common denominator of any set of denominators is infinite.
What is the fraction 9 over 15 minus 1 over 5?
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
What are common denominators?
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
What is the least common denominator of 2 5 and 9?
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.
What is the common factor of 5 over 6 7 over 9 23 over 27 13 over 18?
The common factors of the denominators are 1 and 3, which won't help you. The least common denominator is 54, which will.
What is the common denominator for 1 over 3 and 4 over 9?
To add or subtract fractions, you need a common denominator. In this case, the common denominator for 1/3 and 4/9 is 9. To find a common denominator, you can identify the least common multiple of the denominators, which is 9 in this case. By rewriting 1/3 as 3/9, you can now add the fractions: 3/9 + 4/9 = 7/9.
What is the common denominator of 9 5 and 8?
The common denominator of 9, 5, and 8 is the least common multiple (LCM) of the denominators. To find the LCM, you need to factorize each number into its prime factors: 9 = 3^2, 5 = 5^1, and 8 = 2^3. The LCM is the product of the highest power of each prime factor that appears in any of the numbers, which in this case is 2^3 * 3^2 * 5^1 = 360. Therefore, the common denominator of 9, 5, and 8 is 360.
What is the least common denominator for 9 and 15?
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.
