Answer 3

Let's solve the given arithmetic expressions:

1. 15.10 + (30 - 20): First, we evaluate the expression within parentheses: 30 - 20 = 10. Now, we can add 15.10 to 10: 15.10 + 10 = 25.10.

2. 515.10 + 30 - 20.5: First, we add 515.10 to 30: 515.10 + 30 = 545.10. Then, we subtract 20.5 from the result: 545.10 - 20.5 = 524.60.

Therefore, the results are:

• 15.10 + (30 - 20) = 25.10
• 515.10 + 30 - 20.5 = 524.60
