Explanation

Pi is an irrational number because it cannot be expressed as a simple fraction of two integers. Its decimal representation (3.14159...) continues infinitely without repeating or terminating. Rational numbers can be written as fractions, while odd and even are properties of integers only, not applicable to pi.
