- Irrational Number: Determine if is an irrational number.An irrational number is a number that cannot be expressed as a simple fraction, meaning it's a number that cannot be written as a ratio of two integers. Irrational numbers have non-terminating and non-repeating decimal expansions. Since can be expressed as a ratio of two integers (as shown in Step ), it is not an irrational number.
