Answer 2

.

Rational numbers are those that can be expressed as a ratio (fraction) of two integers; irrational numbers are those that can't be expressed that way.

There is no overlap between the two categories. If a number is rational, it is not irrational, and vice versa.

It's generally easy to prove that a number is rational; you find the fraction and show it. Proving that a number is irrational is harder, and usually requires a proof. For example, mathematicians worked for centuries before proving that pi (π) was an irrational number.
