$\big(\frac{3}{4}-\frac{1}{8}\big)~\colon\big(\frac{1}{2}+\frac{1}{3}\big) = x~\colon\big(1-\frac{2}{5}\big)$
$\big(\frac{6-1}{8}\big)~\colon\big(\frac{3+2}{6}\big)=x~\colon\big(\frac{5-2}{5}\big)$
$\frac{5}{8}~\colon\frac{5}{6} = x~\colon\frac{3}{5}$
$x= \frac{\frac{5}{8}×\frac{3}{5}}{\frac{5}{6}}$
$x= \frac{1}{8}×\frac{3}{1}×\frac{6}{5}$
$x= \frac{1}{4}×\frac{3}{1}×\frac{3}{5} = \frac{9}{20}$

$(3/4-1/8):(1/2+1/3)=x:(1-2/5)$
$(6-1)/8:(3+2)/6=x:(5-2)/5$
$5/8:5/6=x:3/5$
$x=(3/5•5/8)6/5$
$x= 3/8•6/5$
$x= 9/20$
