Pi is approximately equal to 22/7.
Some Europeans celebrate "Pi Approximation Day" on July 22 since they use 22/7 to denote the 22nd of July. Pi doesn't equal 3.14. 3.14 is another approximation to the value of pi. But in the U.S., we celebrate March 14 as "Pi Day," since we use 3/14 to denote March 14. Which is the more accurate approximation to Pi? 22/7 or 3.14? |

How do you compare approximations expressed in different terms?

You know how!
My question was a rhetorical one. Even if you don't know how to express 22/7 in decimal form, the framing of the question suggests what the correct answer is. |

At 26 seconds past 3:09 P.M., we can all have more PI.

It's off by .0012644893 Since .0012644893 is a smaller difference than .0015926535, then 22/7 is a closer approximation. Another reason why the Europeans are kicking our butts in math!

But Archimedes, the "22/7" guy, was Greek.
