Answer 3

Let's solve this step by step:

1. Add the fractions with like denominators:

2/3 + (-7/6) + 5/6 + (-7/12)

First, let's add 2/3 and 5/6: 2/3 + 5/6 = (4 + 5) / 6 = 9/6 = 3/2

Now, let's add the other two fractions: (-7/6) + (-7/12) = (-14 + -7) / 12 = -21/12 = -7/4

Now we can add the results: 3/2 + (-7/4)

To add these fractions, we need to find a common denominator, which is 4. So we'll convert 3/2 to have a denominator of 4: 3/2 * 2/2 = 6/4

Now we can add the fractions: 6/4 + (-7/4) = (6 - 7) / 4 = -1/4

Therefore, the result of the expression is -1/4.
