Answer:

\frac{-6}{7}

Step-by-step explanation:

Let the other number be 'x'

x + \frac{-15}{7} = -3

         x = -3 +  \frac{15}{7}

           = \frac{-3*7}{1*7} +\frac{15}{7}\\\\=\frac{-21}{7}+\frac{15}{7}\\\\= \frac{-21+15}{7}\\\\= \frac{-6}{7}

Sum = -3

First no. = -15/7

Second no. = (-3) - (-15/7)

= -3 + 15/7

= -21/7 + 15/7

= (-21 + 15)/7

= -6/7

The second no. is -6/7.
