Answer 2

Answer:

The other number is -17/3.

Step-by-step explanation:

Given:

The sum of two rational numbers is -5

The first number is 2/3

To find:

The other number

Solution:

We know that the sum of two rational numbers is -5.

Let the other number be x.

$x+2/3=-5$ (add the two numbers to find the sum)

$x=-5-2/3$

$x=(-15-2)/3$

$x=(-15-2)/3$

The other number is -17/3.
