Hello There!
Let me just briefly go over what a "Rational Number" is and what an "Integer" is.
A rational number is a number that can be turned into a fraction. These numbers consist of integers, terminating, and repeating decimals.
An integer is any whole number. Integers can either be positive or negative and they include 0.
An example of a rational number that is not an integer could be 2.5
2.5 can be turned into a fraction but is not an integer because 2.5 is not
a whole number.
