I mean hell, if you multiply .999... by 10 you get 9.999 you multiply it by 1 it equals .999...
there is no changing that. if you multiply 10 and 1 you get 10. showing .999... as anything else is just rounding to the nearest number.

Not true, and you don't round .444... to .4445 where they hell did you learn to round? .4444... = 4/9 and that is not an estimation it is the exact value of .4444..., simply put they are called RATIOnal, which strictly means a ratio of two integers, which is why they are represented by a fraction in the first place.

The real numbers is the name of the system, called such in a response to the imaginary numbers which were found and named first. It doesn't translate literally to mean real.

Which brings me back to the point that the fraction is just the division of the numbers not showing the actual answer because it is simpler it would be the same as saying instead of writing the number 2 i will just write 1+1, they mean the same thing but 1+1 is the incomplete way of doing it. the difference is that with fractions and infinite decimals the fraction is just showing a rounded version of the infinite because it is easier.
It matters not how straight the gate, how charged with punishments the scroll.
