A rational number that IS an integer would be written as a whole number, such as 21 or 999 or -2058. A rational number that ISN’T an integer would have decimals, such as 9.75 or 18.44444, as integers are whole numbers.

Every integer is a rational number, since each integer n can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. However, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
