\[x\ :1\frac{3}{5} = 3\frac{2}{7}\ :2\frac{22}{35}\]
\[x\ :\frac{8}{5} = \frac{27}{3}\ :\frac{92}{35}\]
\[x\ :\frac{8}{5} = \frac{23}{7} \cdot \frac{35}{92}\]
\[x\ :\frac{8}{5} = \frac{23 \cdot 7 \cdot 5}{4 \cdot 7 \cdot 23}\]
\[x\ :\frac{8}{5} = \frac{5}{4}\]
\[x = \frac{5}{4} \cdot \frac{8}{5} =\]
\[x\frac{8}{4} = 2.\]
\[Ответ:\ \ x = 2.\]
