I've wondered about this question for some time now

Read until you have something to write...Write until you have nothing to write...when you have nothing to write, read...read until you have something to write (http://handsonmath.blogspot.com/)

Hi;

I am not sure the question has meaning. Those are mathematical terms, they represent sets. In the real world we have mostly measurements. They are accurate to some specified amount of decimal places. Even though we may be talking about a hypotenuse we say 1.41 miles not square root of 2 miles. Since measurements are terminating decimals the answer in my opinion is Rational.
