It's ok, happens to all of us :)

Answer 6

Ok anyway, since I don't know if your teacher wants a specific format I'm going on a limb here and doing it the logical way.
So first we need to simplify what we can:

\[\frac{ 12 + 2(2^{-1}) }{ 4(5 - 16) }\]

Now by following PEMDAS ( http://www.mathsisfun.com/operation-order-pemdas.html)
we can begin with the parenthesis:

\[2^{-1} \] which can be simplified to \[0.5\] Because a negative integer can be thought of as dividing instead of multiplying, so in this case:\[1 \div 2\] is 0.5

Do you understand so far?
