Answer 1

$\displaystyle 1)1\frac{1}{5}x:1\frac{1}{3}=5\frac{1}{4}:2\frac{1}{3}\\\\ 2\frac{1}{3}*1\frac{1}{5}x=5\frac{1}{4}*1\frac{1}{3}\\\\ \frac{7}{3}*\frac{6}{5}x=\frac{21}{4}*\frac{4}{3}\\\\ 7*\frac{2}{5}x=7\\\\ \frac{14}{5}x=7\\\\ x=\frac{5}{2}=2\frac{1}{2}=2,5\\\\ 2) 1\frac{2}{5}:\frac{5}{6}=x:1\frac{3}{7}\\\\ \frac{6*1\frac{2}{5}*1\frac{3}{7} }{5}=x\\\\ \frac{6*\frac{7}{5}*\frac{10}{7} }{5}=x\\\\ \frac{6*2}{5}=x\\\\ \frac{12}{5}=x\\\\ x=\frac{12}{5}=2\frac{2}{5}=2,4$
