Question

pie is rational no or irrational no?

Answer 1

irrational. Pi never ends and never repeats.

Answer 2

irrational

Answer 3

but it can be written in the form of p/q i.e its value is 22/7 then how is it irrational?

Answer 4

Because that is an approximation, not an exact value. Irrational numbers can not be expressed exactly in decimal form. For example, the number whose square is 2 is EXACTLY the square root of 2
\[\sqrt{2}\]
but its decimal approximation is 1.414
