Answer 1

If someone could just tell me the difference between a rational and irrational
I'm sure I can solve it on my own...

Answer 2

A rational number is one that can be made into a fraction:\[\frac{a}{b}\]where a and b are integers, and b is not 0. If you cannot put it into a fraction with integers, then the number is irrational. Examples of rational numbers:\[2,-8, \frac{3}{4},(3+\sqrt{2})-\sqrt{2}, \sqrt{36}\] Examples of Irrational numbers:\[e,\pi, \sqrt{3}\]

Answer 3

So that means the answer is A! :D
