You're diving into the world of decimals and rounding errors.
When you multiply 3 by 0.333, you get 0.999 because 0.333 is a rounded version of 1/3. The actual decimal representation of 1/3 is 0.33333... (recurring).
If you multiply 3 by the exact value of 1/3, you'd get:
3 x 1/3 = 1
The missing 0.001 is due to the rounding error from using 0.333 instead of the exact value. This is a common phenomenon in math, especially when working with decimals and fractions.

0.9999=1
Not approximately
It is indeed 1
Because cutting a pie to 3 pieces is 1/3
Multiply by 3
It is again 1
There is a whole proof on it google it
