Question

1 5/6 : 1 1/3 = 1 3/5 : х

Answer 1

$1 frac{5}{6} :1 frac{1}{3} = 1frac{3}{5} :x$
$frac{11}{6} : frac{4}{3} = frac{8}{5} :x$
$frac{11}{6}*x=frac{4}{3} *frac{8}{5}$
$frac{11}{6}x= frac{32}{15}$
$x= frac{32}{15}:frac{11}{6}= frac{32*6}{15*11} = frac{192}{165}=1 frac{27}{165} =1 frac{9}{55}$
