Answer 1

A Irrational number

Explanation:

Explanation

Pi is strictly a irrational number , as it is not in the form of
`(P)/(Q)` . i.e not a fraction

Pi is consider from the ration of circumference of circle to its diameter .

and its value is Pi = 3.14159 ,but this value is not repeating

But in case of
`(22)/(7)` its value is 3.142857142857... i.e is this value is reapating its self ,

And
`(22)/(7)` is a rational number, as it is in the form of
`(P)/(Q)`

and if we subtract
`(22)/(7)` from a irrartional number then the resultant is also irrational

Hence we can say that PI -
`(22)/(7)` is a irrational number. Answer
