Answer 1

$\displaystyle\\3\frac{1}{3}x:1,5=4\frac{2}{7}:\frac{3}{14}\\\\\\\frac{10}{3} x:\frac{3}{2} =\frac{30}{7} :\frac{3}{14}\\ \\\\\frac{10}{3} x*\frac{2}{3} =\frac{30}{7} *\frac{14}{3}\\\\\\\frac{10}{3}x *\frac{2}{3} =\frac{10}{1} *\frac{2}{1} \\\\\\\frac{20}{9}x=20\\ \\\\x=20:\frac{20}{9}\\ \\\\x=\frac{20}{1} *\frac{9}{20} \\\\\\x=9$
