It is not exactly equal to any fraction or finite decimal expansion. The fractions 22/7 and 113/355 are good approximations (the first to 2 decimal places, the second to 6). Other frequent approximations are 3.14 and 3.1416. To 50 places, pi is

26433 83279 50288 41971

pi (not pie) is a non-repeating number so has no fraction equivalent. By definition, it is the number of times that the diameter of a circle goes around the circumference of the same circle. It is always the same number for any size circle. It is 3.14159..............
