The common denominator of any two or more whole numbers, such as 9 7 and 3, 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 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
Least Common Denominator of 3 and 9?
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.
Find the lowest common denominator for these fractions and then subtract and simplify. 49 and 13?
The LCD of 4/9 and 1/3 is 9. 4/9 - 3/9 = 1/9
What is the gcm of 3 7 and 9?
It's either GCF (Greatest Common Factor) or LCM (Least Common Multiple).GCF of 3 and 9 is 3, but seven only has 1 as a common factor with the other two, so GCF is 1.LCM of 3 & 9 is 9, and LCM of 9 and 7 is 7 x 9, so LCM is 63.
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
What common denominators of 3 and 5 and 7 and 9?
Only 1.
Least common denominators?
8/9, 5/12, 6/7
How do you solve adding fractions?
To add fractions with a common denominator, you simply add the numerators and keep the denominators the same. For instance, 1/7+3/7 = 4/7 If the denominators are different, you will need to find an equivalent fraction of one of the values that means the denominators can be equal. This is done by multiplying top and bottom of a fraction by the same amount. For instance, if we had 1/3 + 4/9, we would need to multiply top and bottom of the first fraction by 3. That gives us 3/9 + 4/9. Then the addition can be completed normally.

What is the least common denominator for 7 and 9?
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of two or more fractions. Even if you converted your numbers (x) to their fraction equivalents (x/1), the LCD will always be 1.If the 7 and 9 are denominators, the LCD is 63.
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 are the lcd of 45 63 49?
9 by 5- 3 by 3 by 5 9 by 7 - 3 by 3 by 7 7 by 7. you need to go to The Tutoring Center, I used to work there, Lowest Common Denominators are in the first few pages of their workbooks. The LCD for those three numbers is one. They don't share any other factors
Least Common Denominator of 3 and 9?
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.
What is the lead common multiplayer 9 3 7?
The least common multiple of 9, 3 and 7 is 63
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
How do you add fractions and subtract similar and dissimilar fractions?
If the fractions have the same denominator, you can add and subtract them by adding or subtracting the numerator. For instance 2/7 + 3/7 = 5/7 Or 7/9 - 2/9 = 5/9 When the denominators are not the same, you need to multiply both top and bottom of the fractions until the denominators are the same. For instance, if we wanted to do 1/3 + 2/9, we would need to first multiply top and bottom of the first fraction by 3, which makes the question 3/9 + 2/9. Once the denominators are the same, the subtraction or addition can be completed as outlined in the first paragraph.
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.
