For example, there is no number among integers and fractions that equals Square root of√2. WebNote that i is a number, and for any number, the question to ask whether it is rational or not is makes sense. It is not rational, since it is not a ratio of two integers. Hence, it is irrational, as irrational numbers are the complement of the rational ones (complement depending on context, either reals or complex numbers). Share.
