Answer 1

$\frac{6}{z} = \frac{2}{1} \\ 2z = 6 \\ \boxed{z = 3} \\ \\ \frac{z}{t} = \frac{1}{3} \Rightarrow \frac{3}{t} = \frac{1}{3} \\ \boxed{t = 9} \\ \\ \frac{x}{2} = \frac{6}{z} \Rightarrow \frac{x}{2} = \frac{6}{3} \\ x = \frac{2 \times 6}{3} \\ \boxed{x = 4} \\ \\ \frac{2}{y} = \frac{z}{t} \Rightarrow \frac{2}{y} = \frac{3}{9} \\ 3y = 18 \\ y = \frac{18}{3} \\ \boxed{y = 6}$
