A denominator is the bottom number in a fraction. It is also the same thing as the divisor in a division problem. For example: in the fraction 1/2, 2 is the denominator; the mathematical expression of the fraction 1/2 is the same as the mathematical expression of 1 divided by 2. It can also be expressed in ratio form (i.e. 1:2).

How do you know which unit of conversion factor must be the denominator?
The unit that is used in the denominator is the one to cancels the unit that appears in a numerator.
How do you simplify the fraction?
first multiply the denominator to the mixed number. then,when you got the product, add the product to the numerator. then,when you got the sum, copy the sum as numerator and the denominator was the last denominator you used.
A method used to eliminate radicals from the denominator of a fraction?
That is called "rationalizing the denominator". It consists of multiplying the numerator and the denominator by specific terms, which include square roots. Examples:* If the denominator is root(2) (that is, the square root of 2), multiply numerator and denominator by root(2). * If the denominator is root(2) + root(3), multiply numerator and denominator by root(2) - root(3).
Is Least Common Denominator used for subtracting fractions?
Yes.
What 2 operations are used with lowest common denominator?
The least common denominator or (LCD) of two or more fractions is the least common multiple of the denominators.
Why is a one used as a denominator?
It is only rarely used as a denominator.
What is the denominator for 18?
denominator is a name used in fractions not whole numbers e.g 2/5 the denominator is 5
Where is a denominator used?
Many places, but a common one is in adding fractions where we find a common denominator.
The values used with fractions are called?
The numerator and the denominator.

What is a rule for how to find a ratio with a denominator f 1 without using a diagram?
Divide the numerator of the ratio by the denominator. The answer, with a denominator is the required unit fraction. And I have never ever used a diagram - I have no clue what it is or how to use it!
What 2 operations are used with lowest common denominator?
The least common denominator or (LCD) of two or more fractions is the least common multiple of the denominators.
What is the conjugate of a denominator?
This is related to the technique used to eliminate square roots from the denominator. If, for example, the denominator is 4 + root(3), you multiply both numerator and denominator by 4 - root(3). In this case, "4 - root(3)" is said to be the "conjugate" of "4 + root(3)". When doing this, there will be no more square roots in the denominator - but of course, you'll instead have a square root in the numerator.
What is the common denominator of 56 and 7?
A common denominator is 7.A common denominator is 7.A common denominator is 7.A common denominator is 7.
