Answer 2

To simplify the given expression, follow these steps:

Step 1: Perform the operations inside the parentheses. Step 2: Perform the multiplication and division from left to right. Step 3: Perform the addition and subtraction from left to right.

Let's go step by step:

Step 1: Perform the operations inside the parentheses. (28,5/3,04 - 57,195/6,2)

Step 2: Perform the multiplication and division from left to right.

First, divide 28.5 by 3.04: 28.5 / 3.04 ≈ 9.375

Next, divide 57.195 by 6.2: 57.195 / 6.2 ≈ 9.227419355

Step 3: Perform the addition and subtraction from left to right.

Now, we have: (9.375 - 9.227419355)

Finally, subtract the two results: 9.375 - 9.227419355 ≈ 0.147580645

Now, continue with the rest of the expression: 0.147580645 * 1.9 + 2.3 * 0.08

Perform the multiplication first: 0.147580645 * 1.9 ≈ 0.280403226

0.08 * 2.3 = 0.184

Now, perform the addition: 0.280403226 + 0.184 ≈ 0.464403226

So, the final result is approximately 0.4644.
