$\frac{5}{2}$
A rational number can be written as a ratio of two whole integers, but that does not necessarily mean that the number is an integer. For example, $5$ is not evenly divisible by $2$, so $\frac{5}{2}$ is not an integer. However, it can be written as a ratio of two whole integers (5 and 2), so it is certainly rational.
