Explanation

The fraction 355/113 ≈ 3.1415929 is an exceptionally accurate approximation of pi (true value: 3.14159265...), discovered by Chinese mathematician Zu Chongzhi in the 5th century. It's correct to 6 decimal places, making it far more precise than 22/7. The other options (229/73, 336/107, 116/37) are either poor approximations or incorrect. 355/113 is considered one of the best simple fractional approximations of pi.
