The least common denominator is 30. 9/10 = 27/30

135 is the lowest common denominator of numbers 27 and 45.

Learn how to use "common denominators". The common denominator for 27/50 and 18/40 is 200. To get this common denominator, you need to multiply both the numerator and denominator of 27/50 by 4, giving you 108/200. (A fraction remains the same as long as you multiply both the top and bottom numbers by the same number.) To get 18/40 to the common denominator of 200, you have to multiply both the top and bottom by 5. Once you do that, both fractions will have 200 as the denominator, so you can just look to see if the numerator is the same. If not, they aren't equal. Good luck.

The common denominator of any two or more whole numbers, such as 3 9 and 27, 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.

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.

Since there are no common prime factors of 7 and 27, you must multiply them together to get the common denominator. 27 times 7 is 189.

The common denominator of any two or more whole numbers, such as 27 and 99, 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.

27 is an integer and so has no common fractions.

The lowest common denominator of any two or more whole numbers, such as 27 and 50, 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.

The common denominator of any two or more whole numbers, such as 27 7 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.

The common denominator of any two or more whole numbers, such as 27 30 and 28, 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.

The lowest common denominator of any two or more whole numbers, such as 27 and 16, 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.

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

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

STEP ONE: Get a common denominator. STEP TWO: Add or subtract the numerators. STEP THREE: Simplify the result if needed. Notice that 3/27 can be simplified, since the numerator and denominator are both divisible by 3. And that's all there is to it! Final Answer:

For a _positive_ fraction to be proper and in lowest terms, the numerator must be less than the denominator and be relatively prime. For denominator 1: 0 possible numerators. For denominator 2: 1 possible numerator. For denominator 3: 2 possible numerators. For denominator 4: 2 possible numerators. For denominator 5: 4 possible numerators. For denominator 6: 2 possible numerators. For denominator 7: 6 possible numerators. For denominator 8: 4 possible numerators. For denominator 9: 6 possible numerators. Adding all of them together gives 27 positive proper fractions in lowest terms. Symmetrically, there are 27 negative proper fractions in lowest terms. Also, 0/1 is in lowest terms by the above definition. So in total, there are 55 proper fractions in lowest terms with denominator being an integer from 1 to 9.

The common denominator of any two or more whole numbers, such as 27 and 54, 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.

A common denominator is what you get when two different numbers (when you divide or multiply them) have a number in common. This always requires 2 numbers to have something to compare. 27 has the following denominators (by itself): 1, 3 (3*9=27), 9 (3*9=27) So it has a common denominator with at least any other number which is divisible by 1 (which would then be the "lowest common denominator"), 3 and 9.

945 is the lowest common denominator. 3 is the greatest common factor.
