Rational or irrational?  With or without the fragment id?

"Without getting technical, real numbers are all numbers that can be written as a possibly never repeating decimal fraction. For example, all rational numbers are real. Their decimal representations do repeat. Decimal fractions whose representation do not repeat are irrational. " http://www.math.utah.edu/~alfeld/math/numbers.html

I'd say that any explanation that boils down to Cantor probably doesn't belong in there.

Yes, that was wrong -- denumerable would mean they are equivalent to
the set of natural numbers, not real numbers.
