Answer 2

Let's solve each of these arithmetic problems step by step:

1. 1.2488 + 3.7512 = 4.998
2. 48.5363 - 4.494 = 44.0423
3. 51.0277 - 49.2277 = 1.8
4. 6.5133 + 91 = 97.5133
5. 65 - 42.759 = 22.241
6. 449.256 - 0 = 449.256
7. 41.508 - 1.508 = 40
8. 13.128 + 32.211 = 45.339
9. 18.71 + 6.354 = 25.064
10. 8.1132 + 4.341 = 12.4542
11. 30.2 + 9.891 = 40.091
12. 10.1 - 10.085 = 0.015
