I'll give it straight: the following are rational numbers.
Whole numbers
Terminating decimals
Repeating decimals
Improper fractions (and all other fractions)
(Integers, too)
If square root is whole number, square root of a square is perfect, and therefore, rational
Since a rational number is any number that can be written as a fraction, if a mixed number, such as 1 1/2, can be written as a fraction, then it is rational (1 1/2 can be written as 3/2, therefore it is rational)
