Answer 1

Answer:

heya mate ☺

➡ Let the other rational number by x.

According to the question :

$x + ( \frac{ - 13}{6} ) = - 5 \\ \\ = > x - \frac{13}{6} = - 5 \\ \\ = > \frac{6x - 13}{6} = - 5 \\ \\ = > 6x - 13 = - 30 \\ \\ = > 6x = - 30 + 13 \\ \\ = > 6x = - 17 \\ \\ = > x = \frac{ - 17}{6}$

So the other number would be -17 / 6

Verification of my answer :

$\frac{ - 17}{6} + ( \frac{ - 13}{6} ) \\ \\ = \frac{ - 17}{6} - \frac{13}{6} \\ \\ = \frac{ - 17 - 13}{6} \\ \\ = \frac{ - 30}{6} \\ \\ = - 5$

hope it helps u
