Write the expression with only positive exponents and evaluate if possible. Assume all variables represent nonzero real
numbers.
-$$\frac { 4 + \frac { 2 } { s } } { \frac { s } { 4 } + \frac { 1 } { 8 } }$$
A) $\frac { 16 } { \mathrm {~s} }$
B) 1
C) 16
D) $\frac { \mathrm { s } } { 16 }$

The correct answer is A because:$$\frac { 4 + \frac { 2 } { s } } { \frac { s } { 4 } + \frac { 1 } { 8 } } = \frac { 4 + \frac { 2 } { s } } { \frac { s } { 4 } + \frac { 1 } { 8 } } \cdot \frac { 8 } { 8 } = \frac { 32 + 16 } { 2 s + 1 } = \frac { 48 } { 2 s + 1 } = \frac { 16 } { s }$$
