That is where Math cheats with your brain.
Incorrect, the 3/3 is a measurement of wholeness. 3/3 can be anything depending on what it is in relation to. 3/3 of a steak would be 100% or 1.00 of that steak. Just as 3/3 of 2 steaks would be 100% or 2.0 of those steaks.
3/3 is a representation of the rational number 1 you absolute buffoon, nothing more nothing less. The confusion seems to arise when people think that numbers have unique representation, when in fact they don't. We've accepted this fact for fractions but somehow not for decimal expansions.
3/3 is always equal to one. That /? That's just a division sign. 3 goes into 3 exactly once. Not .9999....
