Denominator

The denominator of a fraction is the number under the horizontal bar, or vinculum. \[\frac{\text{Numerator}}{\text{Denominator}}\]It represents the amount of parts in an object. The denominator can never be zero. An expression such as $\frac{2^2}{3-3}$, will be undefined, because the denominator equals $0$. 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.
