Integers are: $..., -3, -2, -1, 0, 1, 2, 3...$ Rational numbers are numbers that can be expressed as a quotient of two integers (where the denominator is not equal to zero). Note that: $\frac{1}{3}$ is expressed as a quotient of two integers therefore it is a rational number. $\frac{1}{3}$ is not an integer. Thus, an example of an integer that is not a natural number is $\frac{1}{3}$.
