If you remember it with denominator first, then it's 113-355, which is relatively easy to remember. :)

It's accurate up to one digit more than that, which is why I called it surprisingly accurate.
But I agree that there is hardly a practical purpose to such numerology.
- Someone 9y agoIt's not numerology, it's number theory. We can directly compute these fractions, and they are in some well-defined way 'best'. To find a better approximation to pi as a rational you will need a denominator of 16604 (52163/16604) See https://en.m.wikipedia.org/wiki/Continued_fraction#Best_rational_approximations https://en.m.wikipedia.org/wiki/Continued_fraction#Best_rati... for an intro to the theory. Reason for that large jump is the 292 in the continued fraction of pi.
