Answer 3

Let's solve the given expressions step-by-step:

1. 680 • (8925/85 + 9407/23)

First, let's simplify the expression inside the parentheses:

8925/85 = 105 9407/23 ≈ 408.8261 (rounded to 4 decimal places)

Now, add the two results:

105 + 408.8261 ≈ 513.8261 (rounded to 4 decimal places)

Now, multiply 680 by the sum:

680 • 513.8261 ≈ 349,497.748 (rounded to 3 decimal places)

So, the result of the first expression is approximately 349,497.748 (rounded to 3 decimal places).

2. 650 • 27 - (4276 + 4863) / 13

First, perform the operations inside the parentheses:

4276 + 4863 = 9,139

Now, divide the result by 13:

9,139 / 13 ≈ 702.2308 (rounded to 4 decimal places)

Next, multiply 650 by 27:

650 • 27 = 17,550

Finally, subtract the result from the previous division:

17,550 - 702.2308 ≈ 16,847.769 (rounded to 3 decimal places)

So, the result of the second expression is approximately 16,847.769 (rounded to 3 decimal places).

The two solutions are:

1. 680 • (8925/85 + 9407/23) ≈ 349,497.748 (rounded to 3 decimal places).
2. 650 • 27 - (4276 + 4863) / 13 ≈ 16,847.769 (rounded to 3 decimal places).
