What to divide to get pi?

Solution:

Pi is an irrational number. It cannot be expressed as a ratio of two integers.

pi, denoted by \(\pi\), is defined as the ratio of the circumference of a circle divided by the diameter of the circle.

It is constant for any circle irrespective of its size.

Value of pi is 3.141592653589793238..... (up to 18 digits)

It is roughly approximated to 3.14159

On other hand 22/7 = 3.1428571...

As the first two digits after the decimal are matching, we roughly estimate pi as 22/7.

The estimation is done for convenient calculations in solving mathematical problems.

Thus, pi cannot be written in p/q form. But it can be approximated to 22/7.
