I'm assuming your asking for a muliplt choice question but I am not sure what the options are so I will explain what a rational number is in hopes that helps. A rational number includes whole numbers 0 and up, natural numbers 1 and up, and numbers that can be simple fractions such as .75 can be 3/4 or .50 which can be 1/2. An example of what is NOT a rational number would be Pi because it is 3.142857142857....
I hope this helped you!
