what does the 7 as centered hexagonal look like?
That would be your drawing.
the fractions represent an infinite repeat going down to infinitely smaller…
I’m sorry, I don’t understand what you mean by that, so I can’t answer your next question…. Every fraction either repeats infinitely, or has a finite number of digits, like 1/4 = 0.25…(you can fill in any amount of zeros after the 5). The first happens, when the greatest common divisor of 10 (because we are using the decimal system!) and the number you are dividing by, is 1 (they have no common factor).
