An irrational number is a number that cannot be expressed as a fraction of two integers (i.e., in the form \(\frac{a}{b}\), where \(a\) and \(b\) are integers and \(b \neq 0\)). The only option in your list that describes a situation that would lead to an irrational number is:
- a fraction with π as the numerator or denominator
This is because π is an irrational number, and any fraction that includes an irrational number (like π) in its numerator or denominator will also be irrational.
