Answer:
[tex]- \frac{3}{4} [/tex]
Step-by-step explanation:
[tex] \frac{ \frac{5}{8} + \frac{3}{4} }{ - \frac{2}{3} - \frac{5}{6} } [/tex]
[tex] = \frac{ \frac{5 + 6}{8} }{ \frac{ - 6 - 5}{6} } [/tex]
[tex] = \frac{ \frac{11}{8} }{ \frac{ - 11}{6} } = \frac{11}{8} \times \frac{ - 6}{11} [/tex]
[tex] = - \frac{3}{4} [/tex]
