Simplify each of the following expressions.

1.  $- 3 ( 2 - 4 ) + 1 \frac { 2 } { 3 }$

   Hint (a):

   Circling terms should help with this one.

2.  $1.6 ( - 7 + 2 ( 5 \frac { 1 } { 4 } ) )$

   Step 1(b):

   $1.6\left(−7 + 2\left(5.25\right)\right)$

   Step 2(b):

   $1.6\left(−7 + 10.5\right)$
