Answer 2

Ответ:

1,5-(-3,5)÷(-1,5+(-3,5))=0,8

Answer 3

Let's simplify the expressions step by step:

1.5 - (-3.5): When you subtract a negative number, it's the same as adding its positive counterpart. So, this expression becomes:

1.5 + 3.5

Now, let's calculate this:

1.5 + 3.5 = 5

So, 1.5 - (-3.5) is equal to 5.

Next, we have:

1.5 + (-3.5): To add a positive number to a negative number, you simply subtract their absolute values and keep the sign of the larger number. In this case:

1.5 + (-3.5) = -2

So, 1.5 + (-3.5) is equal to -2.

Therefore, the final result is:

5 / -2

You can also express this as a fraction:

5 / -2 = -5/2

So, the final result of the given expressions is -5/2 or -2.5.
