We can use those real numbers as if they were equal for most informal situations. It just can't be used like that by anyone who actually does real math.

This is flawed though. 2/3 is not approximately .666~ it is exactly equivalent. Same with 1/3 and .333~.
3/3s is not .999~ it is 1. Real basic maths. how many times does 3 fit into 3? Exactly 1 time, with no remainder.
If you want to try and call .999~ 3/3s that's fine and now 1/3 = .4 and 2/3 = .7 okay?
You can't have it both ways.
This also has nothing at all to do with the math that attempts to prove .999~ = 1.. Just is bugging me.
All you are doing in this case is rounding the number to the nearest 10th.
