= - \frac{16}{5}-\left( \frac{30}{38} \cdot\frac{19}{16} \right)= \\ \\
= - \frac{16}{5}-\frac{30\cdot 19}{38 \cdot 16}= \\ \\
= - \frac{16}{5}-\frac{15\cdot 1}{2 \cdot 8}= \\ \\
= - \frac{16}{5}-\frac{15}{16}= \\ \\ = - \frac{16 \cdot 16}{5 \cdot 16}-\frac{15 \cdot 5}{16 \cdot 5}= - \frac{256}{80}-\frac{75}{80}= \frac{-256-75}{80}=\boxed{-\frac{331}{80}} [/tex]
