An irrational number is defined as a number that cannot be expressed as a ratio of two integers. This means that it cannot be written in the form \( \frac{a}{b} \) where \( a \) and \( b \) are integers and \( b \) is not zero. Examples of irrational numbers include \( \sqrt{2} \), \( \pi \), and \( e \).
