Answer 2

Let's break down the given expression step by step:

1. (-2/1 + 5/1) + 2.2 - 8/2 - 1.05

2. (-2 + 5) + 2.2 - 4 - 1.05 (Adding fractions with common denominators)

3. 3 + 2.2 - 4 - 1.05 (Simplifying the addition)

4. 5.2 - 4 - 1.05 (Adding and subtracting)

5. 1.2 - 1.05 (Subtracting)

6. 0.15 (Final result)

So, the value of the expression is 0.15.
