Work Step by Step
$\frac{4}{2}-\frac{8^2}{16}$ $\longrightarrow$resolve exponent
=$\frac{4}{2}-\frac{64}{16}$ $\longrightarrow$convert to like fraction
=$\frac{4\times8}{2\times8}-\frac{64}{16}$ $\longrightarrow$multiply
=$\frac{32}{16}-\frac{64}{16}$ $\longrightarrow$subtract numerators
=$\frac{-32}{16}$ $\longrightarrow$divide
=$-2$
