Question

geetha tenth student had written PIE asPIE/1 and told that it is a rational number do u agree her

Answer 1

No, I don't agree with her because for a number $\frac{x}{y}$ to be rational, both x and y should be integers and they should be co-primes.
Since $\pi$ is not an integer, $\frac{ \pi }{1}$ is not a rational number.
