What percentage of $$ \frac{\left(\frac{1}{2}\right)^{2}+\left(\frac{1}{2}\right)^{3}}{\frac{1}{4} \cdot\left(1-\frac{1}{3}\right)}-\frac{1}{1+\frac{1}{2}} $$ is $$ \frac{1}{12} \cdot \frac{\left(0,5-\frac{1}{4}\right)^{2} \cdot 8}{0,008 \cdot\left(2+\frac{1}{2}\right)^{4}} $$ ? Round the result to the nearest hundredth. Solve the problem without using a pocket calculator.
