Are you treating complex numbers? If yes, then Z represents a complex number of the form z= x+yi.

And z/6z=x+yi/6(x+yi).

Rationalise:x+yi(x-yi)/6(x+yi)(x-yi)

= (x^2+y^2)/6(x^2+y^2)

=1/6

NB!!! This is if you saw this under complex numbers.

I've only seen Z refer to integers, but like what krassi said, we need the context as well.

Also it may be something from the group theory, I guess.
