but its right

Answer 5

hint:
we can write:
\[\Large \begin{gathered}
- 7\frac{1}{8} = \frac{{ - 7 \times 8 - 1}}{8} = - \frac{{57}}{8} \hfill \\
\hfill \\
- 9\frac{1}{2} = \frac{{ - 9 \times 2 - 1}}{2} = - \frac{{19}}{2} \hfill \\
\end{gathered} \]

Answer 6

so, we have:
\[ \Large - 7\frac{1}{8} - \left( { - 9\frac{1}{2}} \right) = - \frac{{57}}{8} - \left( { - \frac{{19}}{2}} \right) = - \frac{{57}}{8} + \frac{{19}}{2} = ...\]

Answer 7

\[\large - 7\frac{1}{8} - \left( { - 9\frac{1}{2}} \right) = - \frac{{57}}{8} - \left( { - \frac{{19}}{2}} \right) = - \frac{{57}}{8} + \frac{{19}}{2} = ...\]
