Вычислите устно:
$0,6 * \frac{1}{3} = \frac{3}{5} * \frac{1}{3} = \frac{1}{5}$;
$-\frac{2}{5} * \frac{1}{3} = -\frac{2}{15}$;
$-1 * \frac{1}{3} = -\frac{1}{3}$;
$\frac{6}{11} * \frac{1}{3} = \frac{2}{11}$;
$-\frac{3}{7} * \frac{1}{3} = -\frac{1}{7}$;
$-9 * \frac{1}{3} = -3$;
$-2\frac{2}{5} * \frac{1}{3} = -\frac{12}{5} * \frac{1}{3} = -\frac{4}{5}$;
$-3 * \frac{1}{3} = -1$.
$\frac{2}{3} : \frac{3}{5} = \frac{2}{3} * \frac{5}{3} = \frac{10}{9} = 1\frac{1}{9}$;
$-1\frac{2}{3} : \frac{3}{5} = -\frac{5}{3} * \frac{3}{5} = -1$;
$6 : \frac{3}{5} = 6 * \frac{5}{3} = 10$;
$-1\frac{1}{5} : \frac{3}{5} = -\frac{6}{5} * \frac{5}{3} = -2$;
$-3 : \frac{3}{5} = -3 * \frac{5}{3} = -5$;
$-\frac{1}{2} : \frac{3}{5} = -\frac{1}{2} * \frac{5}{3} = -\frac{5}{6}$;
$\frac{9}{11} : \frac{3}{5} = \frac{9}{11} * \frac{5}{3} = \frac{15}{11} = 1\frac{4}{11}$;
$-1 : \frac{3}{5} = -\frac{5}{3} = -1\frac{2}{3}$.
