Question

The sum of two rational numbers is -5. F one of the numbers is -13/6, find the other.

Answer 1

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
