Select the BEST classification for π ???
Is it rational or irrational?
π (Pi) is a famous irrational number. You cannot write down a simple fraction that equals Pi. The popular approximation of 22/7 = 3.1428571428571... is close but not accurate. Another clue is that the decimal goes on forever without repeating.
irrational?
(Wolfram alpha) said it was irrational, they never failed me so...irrational :)

To determine whether π is rational or irrational, we need to understand the definitions of these terms and apply them to π.
1. Rational number: A rational number is any number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero.
2. Irrational number: An irrational number is any real number that cannot be expressed as a simple fraction or ratio of two integers, and its decimal representation does not terminate or repeat.
Now, let's analyze π using these definitions:
π is an irrational number. It cannot be expressed as a simple fraction of two integers, and its decimal representation is non-terminating and non-repeating. In fact, it is often approximated as 3.14159...
Therefore, the best classification for π is "irrational."
