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 .
355/113
22/7
Archimedes estimated the correct value of pi
The equivalency of Pi in a fraction is 22/7.
This is because pi is 22/7 and no one can change the fact and people or mathematicians converted the fraction into decimal which is later estimated as 3.14 or then the decimal will be so long and there will never be an end.
pi is an irrational number and so there is no equivalent fraction.
Consider a distribution with an unknown parameter pi. If the true value of pi is not known but has been estimated, then the estimated value is usually denoted by pi-hat. This is to distinguish between a known parameter and an estimated one.
22/7 is the globally accepted fraction for the decimal number Pi.
The equivalent fraction for Pi is 22/7 or 31/7
Pi is not an exact fraction, it is approximately 22/7. Rather, 21.99114858.........over 7
Pi is an irrational number, can not be represented as a fraction or repeating or terminating decimal, therefore to write it as a number it must be rounded off or estimated. Many formulas can cancel or reduce out the value for pi and make for short work of the number.
The pi decimal is 3.14 and the fraction is 22/7
