Answer 2

To simplify the expression:

-5 1/7 + 4 4/7 + 2 6/7 + (-1 2/7 - 7)

First, let's add the whole numbers together:

-5 + 4 + 2 - 1 = 0

Now, let's add the fractions:

1/7 + 4/7 + 6/7 - 2/7 = (1 + 4 + 6 - 2) / 7 = 9/7

So, the simplified expression is:

0 + 9/7 = 9/7

Therefore, the answer is 9/7.
