Answer 1

Answer:

The other number is -12/5 .

Step-by-step explanation:

Sum of two rational numbers = -5

One of the numbers = -13/5

Let other number be x .

According to the question,

$x \: + \: (\frac{ - 13}{5}) = - 5 \\ => x = - 5 - (\frac{ - 13}{5}) \\ => x = \frac{ - 25 + 13}{5} \\ => x = \frac{ - 12}{5}$
