Pick two of the fractions and find the Least Common Multiple of those two denominators. Then take that number, and find the Least Common Multiple between that and the third denominator. This number will be the Least Common Denominator between the three fractions.

If you don't care to find the Least common denominator, then just take the three denominators, and multiply them together.

Why do you need a common denominator?

Common Denominator means that the denominators in two (or more) fractions are common, or the same. The common denominator is important because before you can add or subtract fractions, the fractions need to have a common denominator.Sometimes fractions have different denominators, like 2/3 and 3/4. If you want to add or subtract them, they need to have the same denominator. In order to do that, you find a common denominator which is the same thing as a common multiple, only with denominators.


Is 8 12elvs smaller than 5 6th?

To compare to fractions, please convert them to a common denominator. (1) Find the common denominator, (2) Convert both fractions to this common denominator, (3) Compare the numerators.


What is the least common denominator for 3 and 7?

There is none. A least common denominator is to be found between or among fractions. 3 and 7 are not fractions.


How do you compare 3 or more fractions?

Find the equivalent fractions with the same denominator (the least common multiple) and then compare the numerators.


What is the least common denominator of 2 and 3?

If you're wanting to find a common denominator between fractions with denominators of 3 and 2, then 3 & 2 have only a common factor of 1, so the least common denominator = 2*3 = 6


What is a common denominator of fractions 34 and 58?

If you mean fractions of 3/4 and 5/8 then the lowest common denominator needed is 8


Is 3 over 4 or 5 over 8 bigger?

Is 1 a common denominator for the fractions 1 3 and 5 6?

No. The smallest common denominator is 6 .


What is the common denominator for 5 over 3?

At least two fractions are needed to determine a common denominator.


What does it mean to get a common denominator?

Sometimes fractions have different denominators, like 2/3 and 3/4. If you want to add or subtract them, they need to have the same denominator. In order to do that, you find a common denominator which is the same thing as a common multiple, only with denominators.

How do you find fractions with the same denominator that are equivalent to the given fractions?

By finding the least common denominator. It's the same process as the least common multiple. Example: 1/2 and 1/3 The LCM of 2 and 3 is 6, so 1/2 = 3/6 and 1/3 = 2/6 To find equivalent fractions, multiply both the numerator and the denominator by the same number.


Two fractions have a common denominator of 8 what could the fractions be?

Any fractions with a denominator of 8. Also, the denominator of one of the fractions might be any factor of 8.


How do you write equivalent fractions with the lowest common denominator?

Example: 2/3 and 3/4 The LCD of 3 and 4 is 12. Multiply the numerator and the denominator of 2/3 by 4 to make 8/12 Multiply the numerator and the denominator of 3/4 by 3 to make 9/12


What is the least common denominator for the fractions 3 and 9?

9 is.


What are the two new fractions that you will add together now that you have a common denominator?

They are equivalent fractions. For example, if you are adding 1/2 and 1/3 and the common denominator is 6, the two new fractions are 3/6 and 2/6 respectively.


What is the least common denominator of 3 and 5?

The Least Common Multiple of 3 and 5 is 15, which would be the denominator to use for fractions with the denominators 3 and 5.


What is the least common denominator of 3 5 and 5 12 they are fractions 3 over 5 and 5 over twelve?

The least common denominator of the fractions 3/5 and 5/12 is 60.


Find equivalent fractions with common denominator and order from least to greatest?

2/3, 1/2, 5/12


Is 2 over 5 more than 3 over 7?

I suggest you do the following: 1) Find a common denominator of 5 and 7. (It need not be the least common denominator; multiplying the two denominators works for our purposes.) 2) Convert both fractions to equivalent fractions with this denominator. 3) Compare the numerators of the fractions thus converted.


What is the least common denominator of 3 5 6?

Sir/Ma'am, denominator are fractions, so the is no common denominator. But the least common multiples is 30


How do you Add and Subtratc fractions mixed with the same denominators and Different denominators?

Different denominators: First, you find a common denominator (it can be the least common denominator, or any common denominator), and convert all fractions involved to equivalent fractions, using the common denominator. For example, 1/4 + 2/3. 12 is a common denominator; you can write this as 3/12 + 8/12.Same denominator: Just add (or subtract) the numerators, and keep the denominator. The above addition would become 11/12. Finally, you may want to check whether you can simplify the answer. Depending on how you (or the teacher) prefers the answer, you may also want to convert to a mixed fraction. In the above example, no such simplification is possible.


How do you plus fractions?

Here is how: You get the fractions and find a common denominator, which means: 1/2 + 1/3 - you find a number in both of the bottom numbers times tables so here with 2 and 3 it would be 6. You then times the number on the top of the fraction by whatever you times-ed the bottom number by to get the common denominator. Here: 1/2 + 1/3 = 3/6 + 2/6. You then add them the top numbers together, place the common denominator underneath and bobs your uncle, you get 5/6.
