Answer 2

To solve the given expression:

(3,8 0,15 – 1,04 : 2,6 + 0,83) + (0,81 : 2,7 + 4,5 0,12 – 0,69)

First, let's perform the operations within each set of parentheses:

For the first set of parentheses: 3,8 * 0,15 = 0.57 (multiplication) 1,04 : 2,6 = 0.4 (division) 0.4 + 0.83 = 1.23 (addition)

For the second set of parentheses: 0,81 : 2,7 = 0.3 (division) 4,5 * 0,12 = 0.54 (multiplication) 0.54 - 0.69 = -0.15 (subtraction)

Now we can substitute the calculated values back into the original expression:

0.57 + 1.23 + 0.3 + (-0.15)

Next, we add the values together:

0.57 + 1.23 + 0.3 - 0.15 = 2.95

Therefore, the result of the expression is 2.95.
