Answer:

Sample Response: A rational number can be expressed as a whole number, a fraction, or decimal that has either terminating or repeating digits. A square root of a perfect square is rational. If it is none of these, then the number is irrational.

An irrational number is one that has no defined ending. EVER. Meaning that as far as we calculate, there will always be infinite more numbers extending away. A rational number is one that has a defined ending, or at least one that we can see. There are two main types: a repeating decimal, or a terminating decimal. An example of a repeating decimal would be 2/3, or 0.6666666 repeating. This number goes on forever, but we know what each number is, so that's okay. An example of a terminating decimal is one that just...ends, such as 1/2, which in decimal form is just 0.5.

Hope this helped :)
