Let Other rational number be X

$\frac{5}{6} + x = \frac{ - 2}{9} \\ \\ = > x = \frac{ - 2}{9} - \frac{5}{6} \\ \\ = > x = \frac{ - 12 - 45 }{54} \\ \\ = > x = \frac{ - 67}{54}$

Answer:

Step-by-step explanation:

The sum of two rational number = - 2/9

that is,                              a  +  b    =   - 2/9

                                         5/6  + b  =  - 2/9

                                                b = -2/9  - 5/6

                                                   =  -4/18  - 15/18

                                                   =  -19/18

so the other number is -19/18
