Answer 2

• $\bf{\frac{-5}{8}}\:+\:{\frac{8}{9}}\:+\:(\:{\frac{-11}{2}}\:)$

${ }$

$\:\:\:\:\:\::\:\Longrightarrow\sf{\frac{-5}{8}}\:+\:{\frac{8}{9}}\:+\:(\:{\frac{-11}{2}}\:)$

$\:\:\:\:\:\::\:\Longrightarrow\sf{\frac{-5}{8}}\:+\:{\frac{8}{9}}\:-\:{\frac{11}{2}}$

$\:\:\:\:\:\::\:\Longrightarrow\sf{\frac{-40\:+\:64\:-\:396}{72}}$

$\:\:\:\:\:\::\:\Longrightarrow\sf{\frac{-436\:+\:64}{72}}$

$\:\:\:\:\:\::\:\Longrightarrow\sf{\frac{\cancel{-372}}{\cancel{72}}}$

$\:\:\:\:\:\::\:\Longrightarrow\sf{\frac{\cancel{-1686}}{\cancel{36}}}$

$\:\:\:\:\:\::\:\Longrightarrow\sf{\frac{-93}{18}}$
