Вычислите произведение:
а) $1\frac{1}{5} * \frac{1}{6}$;
б) $2\frac{2}{5} * \frac{2}{3}$;
в) $\frac{7}{9} * 4\frac{1}{2}$;
г) $\frac{3}{7} * 3\frac{1}{3}$;
д) $1\frac{1}{2} * 1\frac{1}{3}$;
е) $2\frac{1}{2} * 1\frac{3}{5}$;
ж) $7\frac{2}{3} * 2\frac{1}{4}$;
з) $5\frac{2}{5} * 1\frac{1}{9}$.
$1\frac{1}{5} * \frac{1}{6} = \frac{6}{5} * \frac{1}{6} = \frac{1}{5}$
$2\frac{2}{5} * \frac{2}{3} = \frac{12}{5} * \frac{2}{3} = \frac{4}{5} * \frac{2}{1} = \frac{8}{5} = 1\frac{3}{5}$
$\frac{7}{9} * 4\frac{1}{2} = \frac{7}{9} * \frac{9}{2} = \frac{7}{1} * \frac{1}{2} = \frac{7}{2} = 3\frac{1}{2}$
$\frac{3}{7} * 3\frac{1}{3} = \frac{3}{7} * \frac{10}{3} = \frac{1}{7} * \frac{10}{1} = \frac{10}{7} = 1\frac{3}{7}$
$1\frac{1}{2} * 1\frac{1}{3} = \frac{3}{2} * \frac{4}{3} = \frac{1}{1} * \frac{2}{1} = 2$
$2\frac{1}{2} * 1\frac{3}{5} = \frac{5}{2} * \frac{8}{5} = \frac{1}{1} * \frac{4}{1} = 4$
$7\frac{2}{3} * 2\frac{1}{4} = \frac{23}{3} * \frac{9}{4} = \frac{23}{1} * \frac{3}{4} = \frac{69}{4} = 17\frac{1}{4}$
$5\frac{2}{5} * 1\frac{1}{9} = \frac{27}{5} * \frac{10}{9} = \frac{3}{1} * \frac{2}{1} = 6$
