Answer 3

Sure, I'd be happy to help you with these calculations:

1. -3/5 + (-1/5) = -4/5
2. -2/7 + 1/7 = -1/7
3. 3/8 + (-1/8) = 2/8 = 1/4
4. -2.7 + (3/7) ≈ -2.7 + 0.42857 ≈ -2.27143
5. -3/5 + 4/5 = 1/5
6. -9/10 + 3/7 ≈ -0.9 + 0.42857 ≈ -0.47143
7. -1/4 + (-3/4) = -4/4 = -1
8. -7/9 + 2/9 = -5/9
9. 3/7 + (-6/7) = -3/7

Please note that in some cases, I've rounded the decimals to a certain number of decimal places for simplicity. If you need more precise results, feel free to perform the calculations using more decimal places.
