Answer 2

To solve this expression, let's break it down step by step:

1. First, let's simplify the expression inside the parentheses: (2,7 - 0,8) = 1,9. So the expression becomes: 1,9 * 2 1/3 + 0,125 : 2 1/2 + 0,43.

2. Next, let's simplify the mixed number: 2 1/3 = 7/3. Now the expression is: 1,9 * (7/3) + 0,125 : 2 1/2 + 0,43.

3. Multiplication takes precedence, so let's perform the multiplication: 1,9 * (7/3) = 1.9 * (7/3) = 4.1333... (rounded to 4 decimal places). The expression now becomes: 4.1333... + 0,125 : 2 1/2 + 0,43.

4. Division takes precedence over addition, so let's solve the division: 0,125 : 2 1/2. To divide by a mixed number, we first convert it to an improper fraction: 2 1/2 = 5/2. Now the expression becomes: 4.1333... + 0,125 : (5/2) + 0,43.

5. Let's solve the division: 0,125 : (5/2) = 0,125 * (2/5) = 0,025. The expression now becomes: 4.1333... + 0,025 + 0,43.

6. Finally, let's perform the addition: 4.1333... + 0,025 + 0,43 = 4.5883... (rounded to 4 decimal places).

Therefore, the result of the expression (2,7-0,8)*2 1/3 + 0,125 : 2 1/2 + 0,43 is approximately 4.5883.
