If 1/3 < z <2/3 , then what is the value of z?

(1) When positive integer x is divided by 2, the result is z --> $$z=\frac{x}{2}$$ --> $$\frac{1}{3}<\frac{x}{2}<\frac{2}{3}$$ --> $$\frac{2}{3}<x<\frac{4}{3}$$ --> since $$x$$ is an integer then $$x=1$$ (the only integer in that range) --> $$z=\frac{x}{2}=\frac{1}{2}$$. Sufficient.

(2) When positive even integer y is divided by 12, the result is z --> $$z=\frac{y}{12}$$ --> $$\frac{1}{3}<\frac{y}{12}<\frac{2}{3}$$ --> $$4<y<8$$ --> since $$y$$ is an even integer then $$y=6$$ (the only even integer in that range) --> $$z=\frac{y}{12}=\frac{1}{2}$$. Sufficient.
