Well, the answer to this question would be: A rational number both the numerator and the denominator are whole numbers, but the denominator is not equal to zero. Whereas a irrational number cannot be written in a fraction. Not to mention, a irrational number cannot be expressed in a ratio with two integers. though, I'm no math whizz, I'm 100% sure this is correct :)
