Answer:

Let \ the \  number \ be = x\\sum \ of \ 2 \ rational \ numbers = -5\\\\x + \frac{-13}{6} = -5\\\\x - \frac{13}{6} = -5\\\\

x = -5 + \frac{13}{6} = \frac{-30 + 13}{6} = -\frac{17}{6}

The other rational number = -17/6

<h3>Answer:   -17/6</h3>

======================================================

Work Shown:

  • A = first rational number = -13/6
  • B = second rational number = unknown

A+B = -5 ... since the sum of both is -5

B = -5-A

B = -5-(-13/6)

B = -5+13/6

B = -30/6 + 13/6

B = (-30+13)/6

B = -17/6  is the answer

---------------

Extra info:

This improper fraction converts to the mixed number -2 & 5/6

In decimal form, it's approximately equal to -17/6 = -2.833
