A rational is a number that can be expressed as the ratio of two integers.

ℚ

In mathematics, a rational number is any number that can be expressed as the quotient or fraction p/q of two integers, p and q, with the denominator q not equal to zero. Since q may be equal to 1, every integer is a rational number. The set of all rational numbers is usually denoted by a boldface Q (or blackboard bold (\mathbb{Q} in LaTeX), Unicode ℚ); it was thus denoted in 1895 by Peano after quoziente, Italian for "quotient".

Which versions of Python use rational arithmetic by default?

If I type the following into either the Python 2.7.1 shell or the 3.3.2 shell: a = 0.1 b = 0.1 (a + b) == 0.2 it returns the value true. From stackoverflow and this video from MIT, I was under the impression that this would return false, since…

constructor Rational in class Rational cannot be applied to the given types?

So the gist of this program is to create a Rational class so that when you run it, a GUI input will come up and ask for a numerator and a denominator. It will then return the reduced fraction. But I keep getting this error message and I don't know…
