Answer 1

Answer:

The other number is -128/17

Step-by-step explanation:

Let the unknown number be x,

$\tt \longmapsto \: x + \frac{ - 8}{17} = - 8$

$\tt \longmapsto \: x = \frac{ - 8}{1} + \frac{8}{17}$

$\tt \longmapsto \: x = \frac{ - 136 + 8}{17}$

$\tt \longmapsto \: x = \frac{ - 128}{17}$
