Answer 2

It appears that you have provided a series of mathematical expressions and equations. Let's go through each one of them:

1. -7 ÷ 5 = -0.15
2. (-1, 21) ÷ (-1, 1) - It's not clear what operation is intended here, as the format seems to be incorrect. If you can provide more information, I can help you better.
3. -4 ÷ 2 = -0.07
4. 36 ÷ (-0.4) = -90
5. -2 ÷ 7 = -0.2857142857 (repeating decimal)
6. -600 ÷ 1.2 = -500
7. 0 ÷ (-5) = 0
8. -4.9 ÷ 0.007 = -700
