22/7 or 3 1/7 is the closest known fraction
A rational number is a fraction with an integer in the numerator, and a non-zero integer in the denominator. If you consider pi/2, pi/3, pi/4 (common 'fractions' of pi used in trigonometry) to be 'fractions', then these are not rational numbers.
Irrational numbers are numbers that can't be expressed as fractions and are never ending decimals that can't be expressed as fractions as for example the value of pi as in a circle.
pi is an irrational number and so there is no equivalent fraction.
No. For example, pi/2 is a fraction which is not rational.

No. pi/2 is a fraction but, since pi is irrational, so it pi/2.

They are both about math, i guess
Pi is 22/7. Therefore, the equation for finding the circumference of a circle using fractions is: 22/7 mutiplied by the diameter of the circle :)

pi (π) = 3.14159265
There are an infinite number of fractions that could be used as estimates for (pi).Some are closer to the accurate value, some are not so close.Personally, I like 22/7 . It's easy to remember, easy to use, and only 0.04% too big .
Pi
pi is irrational so there can be no fraction that is equivalent. 22/7 is often used as a simple approximation.
Numbers that can be expressed as fractions consisting of two integers are rational numbers. sqrt(2)/3 or pi/4 are fractions but they are not rational.
