  A.  -(1 4/6 +2 1/6)

  B.  -3 5/6

Step-by-step explanation:

A. Real number properties let us factor out a factor of -1, and they let us rewrite 2/3 as 4/6. Using these, an equivalent expression is ...

  -(1 2/3 +2 1/6) = -(1 4/6 +2 1/6)

__

B. The sum is ...

  -((1+2) +(4/6 +1/6)) = -(3 +(4+1)/6) = -3 5/6
