pi mathmatics

Here are some rational approximations to pi with decimal equivalents given to 9 decimal places:

.

Well... Let's see...  3.141592654 (not  3.1415926353)

As a mixed number this would be \(3{141592654\over1000000000}\)

This DEFINITELY can be simplified, so let's see what we can find.

The most simplified answer is \(3{70796327\over500000000}\)

\(\frac{22}{7}\)

I think that is the fraction.

428,224,593,349,304 / 136,308,121,570,117==3.14159265358979323846264338327(569...)

Accurate to 29 decimal places!!!!.
