"Rational" is an adjective and so there cannot be "a rational" (and certainly not "an rational"). Any answer would depend on whether the question was about a rational number, a rational person, a rational argument or "a rational" combined with some other noun.

Well, honey, a rational number is any number that can be expressed as a fraction, where the numerator and denominator are both integers. So, if you can write 15 over 4 as a fraction (15/4), then yes, it's a rational number. Don't stress, math can be a real pain in the behind sometimes, but this one's a no-brainer.
