Answer 3

Let's solve the expression step by step:

Step 1: Perform the operations inside the parentheses. 3 - 2.8 * (3/7) = 3 - 2.8 * 0.42857142857 ≈ 3 - 1.2000000006 ≈ 1.8 (rounded to one decimal place)

Step 2: Divide 1.8 by 0.6 1.8 / 0.6 = 3

Step 3: Perform the operations outside the parentheses. 8,25:1,1 - 3 = 7.5 - 3 = 4.5

So, the result of the expression is 4.5.
