#### Answer

An example is one-half (1/2). See image and explanation.

#### Work Step by Step

An example of a fraction is "one-half", represented as:
$\displaystyle \frac{1\leftarrow numerator}{2\leftarrow denominator}$
In this case the denominator "2" represents the number of equal parts in the whole (e.g. imagine a pie divided in two equal parts). The numerator "1" represents the number of parts in the denominator (e.g. out of 2) that are selected. In this case, we have one out of two parts, or one-half. For example, this could represent half of a pie. See image.
