The denominator is the bottom number in a fraction, and we can say that the denominator is the divisor of a fraction. It defines the number of equal parts an item is divided into.

The meaning of denominator is the divisor of a fraction or the number which is below the line in a fraction. It is just the opposite of a numerator, which lies above the line in a fraction. Now you may consider, what a fraction is? The fraction is one part when a whole is divided into equal parts. Mathematically its is shown by the division of two numbers. Let’s go through some examples and you recall all the divisibility rules to make sure you understand the formulas easily.

For example, 1/4 is one part out of the four equal parts created from that one whole thing. So here, 1 is the numerator and 4 is the denominator. In this article, let us discuss the denominator definition, the comparison between the numerator and the denominator, how to find the least common denominator when the problem involves two or more fractions and rationalizing the denominator with more solved examples.

Equivalent Fractions

Some fractions may look different, but are really the same, for example:

^4/8	=	^2/4	=	^1/2
(Four-Eighths)		(Two-Quarters)		(One-Half)
	=		=

It is usually best to show an answer using the simplest fraction ( ¹/₂ in this case ). That is called
