$$\frac{ 2 }{ x } = \frac{ 7 }{ y } = \frac{ 9 }{ z } = \frac{ 84 }{ 356 }$$
$x=\frac{178}{21}\text{ and }y=\frac{89}{3}\text{ and }z=\frac{267}{7}$
$x = \frac{178}{21} = 8\frac{10}{21} \approx 8.476190476$
$y=\frac{89}{3}\text{ and }z=\frac{267}{7}$
$z = \frac{267}{7} = 38\frac{1}{7} = 38.142857142857146$
$y=\frac{89}{3}\text{ and }x=\frac{178}{21}$
