Answer 2

Let's solve each of these expressions step by step:

1. (860 + 40) - (560 - 60) / 100 First, calculate the values inside the parentheses: = (900) - (500) / 100 Now, perform the subtraction and division: = 900 - 5 = 895

2. (920 - 50) + (480 + 24) / 62 First, calculate the values inside the parentheses: = (870) + (504) / 62 Now, perform the addition and division: = 870 + 8.12903225806 (approximately) ≈ 878.13

3. 400 - (270 + 30) * (400 - 396) First, calculate the values inside the parentheses: = 400 - (300) * (4) Now, perform the multiplication and subtraction: = 400 - 1200 = -800

4. 510.6 - (780 - 20) + (230 + 470) First, calculate the values inside the parentheses: = 510.6 - 760 + 700 Now, perform the addition and subtraction: = 510.6 - 60 + 700 = 450.6 + 700 = 1150.6

So, the results of the expressions are as follows:

1. 895
2. Approximately 878.13
3. -800
4. 1150.6
