Answer 3

To solve these arithmetic expressions, let's calculate them one by one:

1. 12 + 17 + 18 + 20 + 28 = 95

2. 260 + 290 + 200 + 150 = 900

3. 64 + 32 + 15 + 7 + 39 + 303 + 100 + 80 = 640

4. 10 + 20 + 30 + 40 + 50 + 60 + 70 + 80 + 90 = 450

Therefore, the results are:

1. 95
2. 900
3. 640
4. 450
