These fractions are examples of rational numbers.

A *rational number* is a number that can be written in the form $\frac{p}{q}$, where *p* and *q* are integers and *q* is not 0. That is, a rational number is a number that can be written as a *ratio* of integers. All the integers, fractions, decimals, and percents you have worked with are rational numbers.

All rational numbers can be written as decimals that either terminate (end), like those in the first column, or repeat forever in a pattern, like those in the second column.
