No. I don't agree with Geetha's argument.
Pi(π) is an irrational number with its value equal to 3.14159...(no definite ratio)
If we consider, π/1 ,even then it is not a rational number.
Its because, rational number is a number which can be written in simple fractions and not anyway in terms of decimals.
In this case, π/1 = 3.14159.../1 (which isn't in simple fractions but in decimals)
Hence, π/1 is not a rational number.
