Answer 2

Let's break down the expression step by step:

1. Calculate the value inside the parentheses first: 1310 - 565020 = -563710

2. Now, calculate the value outside the parentheses: (806 * 450 + 430 * 180) = (362700 + 77400) = 440100

3. Finally, divide the value outside the parentheses by the value inside the parentheses: 440100 / (-563710) ≈ -0.7808

So, the result of the expression (806 * 450 + 430 * 180) / (1310 - 565020 / 657) is approximately -0.7808.
