2.
$- 7 \frac{2}{3}$

Answer 2

(-1/2)+(-5)= -5,5
(-7)+(-2/3)= -7,6

Answer 3

Let's calculate the expressions step by step:

1. (-1/2) + (-5):

To add these two numbers, we need a common denominator, which is 2 in this case.

(-1/2) + (-5) = (-1/2) + (-10/2) = (-1 - 10) / 2 = -11 / 2 = -5.5

So, (-1/2) + (-5) equals -5.5.

2. (-7) + (-2/3):

To add these two numbers, we need a common denominator, which is 3 in this case.

(-7) + (-2/3) = (-7 * 3) / 3 + (-2/3) = (-21 - 2) / 3 = -23 / 3

So, (-7) + (-2/3) equals -23/3, which is an improper fraction. It can also be written as -7⅔ or approximately -7.67.

Therefore, the final results are:

(-1/2) + (-5) = -5.5 (-7) + (-2/3) = -23/3 or -7⅔ or approximately -7.67
