Why isn't the value of pi accurately equal to 22/7?

22/7 is an approximation of pi. It's not the real thing because pi cannot be expressed as a ratio of integers, but it's near enough for many purposes. There are other approximation like that such as 333/106, and 355/113. read more

Best Answer: Pi is not equal to 22/7 nor was it invented by William Jones. pi was first approximated (according to egyptologists) by the egyptians who built the pyramids. archimedes then had his own approximation these approximations were made more and more accurate over time. with more decimals being added. read more

The value is so large that it is difficult to perform calculations using the above value. This value is approximate to 22/7 or 3.14. read more
