Is Pi(π) rational or irrational?
Sometimes we use π=22/7 which is a popular
approximation
π=3.14159265358..
22/7 =3.142857142857...
But π and 22/7 are close but not accurate.
Rational Numbers - P/Q when Q is not equal to 0.
Let x =3333333......(1)
10x =33333333......(2)
Equation (2) - (1)
9x =30
x= 30/9 which is in form of P/Q and x 33.3333...
The digit '3' is repeating itself and that's why it
can be written as 100/3.
When it's π, the value is 3.14159265358... The order
of digits will not repeat itself in it but in 22/7
3.142857142857.... you can see that 142857... is
repeating itself that's why 22/7 is rational but π
is irrational.

All right
