We have,

Given number $=\frac{-7}{8}$

The sum of the given number and the required number $=\frac{5}{9}$
$\therefore$ required number = sum of the numbers - given number
$=\frac{5}{9}-\left(\frac{-7}{8}\right)$
$=\frac{5}{9}+\frac{7}{8}$
$=\frac{40+63}{72}$
$=\frac{103}{72}$
The required number $=\frac{103}{72}$
