A **rational number** can be written as a fraction $\frac{p}{q}$,

where $p$ and $q$ are integers and $q$ does not equal zero.

Integers, fractions, and repeating or terminating decimals are rational numbers.

**Integers** are whole numbers and their opposites {..., -3, -2, -1, 0, 1, 2, 3, ...}.

**Whole numbers** are rational numbers greater than or

equal to zero that do not have a fraction or decimal {0, 1, 2, 3, ...}.
