Since our numerical system is based upon 10 digits, every number divided by nine wil cause an infinite loop of numbers one over nine is 0.1111111... two over nine is 0.22222222... since eighth over nine is 0.888888888... nine over nine is 0.99999999... but nine over nine is 1 so in your case eleven over nine will cause a infinite loop of 1.222222222222222222... Point is an accurate decimal form of eleven over nine or any other digits over nine is impossible.
