Вычислите:
а) $\frac{\frac{1}{2} * \frac{2}{3}}{\frac{1}{3}}$;
б) $\frac{\frac{5}{8}}{\frac{3}{4} * \frac{1}{2}}$;
в) $\frac{1}{\frac{1}{2} * \frac{1}{6}}$;
г) $\frac{\frac{1}{4} * \frac{1}{7}}{\frac{1}{2} * \frac{1}{14}}$.
$\frac{\frac{1}{2} * \frac{2}{3}}{\frac{1}{3}} = \frac{\frac{1}{3}}{\frac{1}{3}} = \frac{1}{3} * \frac{3}{1} = 1$
$\frac{\frac{5}{8}}{\frac{3}{4} * \frac{1}{2}} = \frac{\frac{5}{8}}{\frac{3}{8}} = \frac{5}{8} * \frac{8}{3} = \frac{5}{3} = 1\frac{2}{3}$
$\frac{1}{\frac{1}{2} * \frac{1}{6}} = \frac{1}{\frac{1}{12}} = 1 * \frac{12}{1} = 12$
$\frac{\frac{1}{4} * \frac{1}{7}}{\frac{1}{2} * \frac{1}{14}} = \frac{\frac{1}{28}}{\frac{1}{28}} = \frac{1}{28} * \frac{28}{1} = 1$
