I was asking about 1/3 = .3333 .....
I studied engineering, not goofy math problems.
.333 .... is a repeating decimal approximation of 1/3. Every time you use it in a calculation you introduce a rounding error, which you MUST be aware of if you are designing something (like a bridge). You illustrated this in your post when you got the answer 1=.999 ....
It is better to use the rational relationship as much as possible because it is accurate and the decimal is an approximation.
