My calculator gives a value 3.14----
I guess you could use 3 14/100=314/100=157/50  close but no cigar!

anonymous · Answer

22/7 right?

anonymous · Answer

I mean thats the standard version.

anonymous · Answer

It's a reasonable estimate for many uses but is not exact; as radar said, pi is irrational and cannot be expressed (exactly) as a fraction.

anonymous · Answer

Well not exactly, but it works dandy with circles.

anonymous · Answer

Pi is an irrational number and cannot be expressed as a fraction, however there have been fractional approximations of Pi who have been discovered by various mathematicians, they include:
22/7 (The most common)
223/71 (correct upto two decimal places)
339/108 (which is also approximately correct up to two decimal places if rounded off)
62832/20000 ( a really approximate fraction)

and there might be others too, which i might not be aware of, or studied yet.
