Because it is a non-repeating, non-terminating decimal.

22/7 is often used for pi, but it is only an approximation; there is no fraction that exactly equals pi.

Why pie is a rational or an irrational number?

First of all 'pi' is spelled as 'pi' . NOT 'pie' ; that is the meat pie of apple pie that you eat. 'pi' is the small case classical Greek letter 'p' and mean 'proportion'. It is the proportional constant between a circles diameter and circumference. 'pi' is an IRRATIONAL number. Casually this means, that the decimal digits go to infinity, and the digits are NOT in a any regular order. . More formally 'irrational' means that you cannot form an exact ratio from it's decimal digits. pi= 3.14 , 3.1416, 3.14592654, 22/7 are all approximations of 'pi'. Super . Duper Computers have calculated 'pi' to billions of places and still going. !!!!!
