Answer»

Given,

  • SUM of TWO rational NUMBER = -5
  • One of the rational number = -13/6

To find : the another rational number

So, LET the unknown rational number be x

Then,

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

Hence,

  • The unknown rational number is -17/6
