Answer 2

To evaluate the expression:

A) -8 : 0.4 + 0.6 : (-0.5)

First, let's simplify the expression step by step:

1. Divide -8 by 0.4: -8 / 0.4 = -20

2. Divide 0.6 by -0.5: 0.6 / (-0.5) = -1.2

Now, let's substitute the results back into the expression:

-20 + (-1.2)

To add these two numbers, we can simply sum them:

-20 + (-1.2) = -21.2

Therefore, the value of the expression is -21.2.
