Answer:

AB = 12

2x = 6 . . . . . . subtract 2x

4x = 12 . . . . . .multiply by 2

$( \frac{9}{32} \times \frac{5}{6} )\times \frac{8}{15} \\$
Let's do the bracket part first,
and solve further as shown,
$( \frac{3}{32} \times \frac{5}{2}) \times \frac{8}{15} \\ = \frac{15}{64} \times \frac{8}{15} \\ = \frac{8}{64} \\ = \frac{1}{8}$
