Answer 2

Step-by-step explanation:

Let's denote the other rational number as x.

We know that the sum of the two rational numbers is -5, so we can write:

2/3 + x = -5

To solve for x, we need to isolate it on one side of the equation. We can do this by subtracting 2/3 from both sides:

x = -5 - 2/3

To simplify the right-hand side, we need to find a common denominator for -5 and 2/3. The least common multiple of 3 and 1 is 3, so we can write:

x = -15/3 - 2/3

x = -17/3

Therefore, the other rational number is -17/3.
