The denominator of a fraction is the number under the horizontal bar, or vinculum. ![\[\frac{\text{Numerator}}{\text{Denominator}}\]](http://latex.artofproblemsolving.com/5/b/8/5b8958566dc7d3c70df5ccb970a7e0a741ce91c2.png)
It represents the amount of parts in an object. The denominator can never be zero. An expression such as 
, will be undefined, because the denominator equals 
. As the denominator of a fraction gets smaller, the value of the fraction will get larger. Conversely, as the denominator of a fraction gets larger, the value of the fraction gets smaller.
If the absolute value of the denominator is greater than the absolute value of the numerator of a fraction, it is a proper fraction. If it is the other way around, the fraction is improper.
