Answer 2

Let's solve the expression step by step:

1. (23, 79 : 7,8 - 6,8 : 17) To perform the division, we'll convert the comma-separated numbers into decimals. The expression becomes:

(23.79 / 7.8 - 6.8 / 17)

Now, let's solve each part of the expression:

a. 23.79 / 7.8 ≈ 3.05769230769 (rounded to 11 decimal places) b. 6.8 / 17 ≈ 0.4 (rounded to 1 decimal place)

Now, the expression becomes:

(3.05769230769 - 0.4)

2. Multiplication and subtraction Next, we'll multiply the result of the above expression by 3.04 and then subtract 2.04 multiplied by 0.85:

(3.05769230769 - 0.4) * 3.04 - 2.04 * 0.85

Now, let's calculate the remaining parts:

a. (3.05769230769 - 0.4) * 3.04 ≈ 8.18961538462 (rounded to 11 decimal places) b. 2.04 * 0.85 = 1.734 (rounded to 3 decimal places)

Finally, we have:

8.18961538462 - 1.734 ≈ 6.455 (rounded to 3 decimal places)

So, the result of the expression is approximately 6.455.
