Let's break this down step by step:

1) First, let's simplify the expression inside the parentheses:
0,04 - 3 4/25

Convert 3 4/25 to an improper fraction:
3 = 75/25
75/25 + 4/25 = 79/25

Now, subtract:
0.04 - 79/25 = 0.04 - 3.16
0.04 - 3.16 = -3.12

2) Now, let's substitute this back into the original expression:
-3,075 ÷ 1.5 + 0.5 × (-3.12)

3) Perform the multiplication first:
0.5 x (-3.12) = -1.56

4) Now, substitute this back into the expression:
-3,075 ÷ 1.5 - 1.56

5) Finally, perform the division:
-3,075 ÷ 1.5 = -2050
-2050 - 1.56 = -2051.56

Therefore, the solution to the expression is approximately -3.61.
