$\frac{1}{12}$

$\frac{3}{11}$

$\frac{2}{11}$

$=1 ×\frac {2}{3}$

$=\frac {2}{3}$

$=\frac {25}{9} \div (\frac {5}{4} ×\frac {4}{5})$

$=\frac {25}{9}$

$=(\frac {5}{8} ×4) ×(\frac {20}{7} ×\frac {7}{10})$

$=\frac {5}{2} ×2$

$=5$

$\begin {aligned}解：x&=8÷\frac {4}{5}\\x &=10\end {aligned}$

$\begin {aligned}解：x&=\frac 56-\frac 14\\x &=\frac {7}{12}\end {aligned}$

$\begin {aligned}解：x&=\frac {4}{15}×\frac {5}{8}\\x &=\frac {1}{6}\end {aligned}$
