Answer 2

Let's solve these arithmetic expressions step by step:

1. -5/8 + (-7/8) = (-5/8) + (-7/8) = -12/8 = -3/2

2. 6/7 + (-1/7) = (6/7) + (-1/7) = 5/7

3. -2/6 + (-1/2) = (-2/6) + (-3/6) = -5/6

4. -7/10 + 1/5 = (-7/10) + (2/10) = -5/10 = -1/2

5. 5/6 + (-1/9) = (5/6) - (1/9) = (15/18) - (2/18) = 13/18

6. 3/7 + 2/3 = (3/7) + (14/21) = (9/21) + (14/21) = 23/21

7. -11/12 + 7/18 = (-11/12) + (7/18) = (-22/24) + (14/24) = -8/24 = -1/3

8. -11/18 + (-8/27) = (-11/18) + (-8/27) = (-33/54) + (-16/54) = -49/54

So, the simplified results for each expression are as follows:

1. -3/2
2. 5/7
3. -5/6
4. -1/2
5. 13/18
6. 23/21
7. -1/3
8. -49/54
