Вычислите:
а) $2\frac{3}{4} * (-8)$;
б) $4\frac{1}{3} : (-13)$;
в) $-1\frac{7}{9} * (-3)$;
г) $-3\frac{1}{7} : (-2)$;
д) $-4\frac{1}{12} * 6$;
е) $-1\frac{7}{8} : 5$.
$2\frac{3}{4} * (-8) = -\frac{11}{4} * 8 = -11 * 2 = -22$
$4\frac{1}{3} : (-13) = -\frac{13}{3} : 13 = -\frac{1}{3}$
$-1\frac{7}{9} * (-3) = \frac{16}{9} * 3 = \frac{16}{3} = 5\frac{1}{3}$
$-3\frac{1}{7} : (-2) = \frac{22}{7} : 2 = \frac{11}{7} = 1\frac{4}{7}$
$-4\frac{1}{12} * 6 = -\frac{49}{12} * 6 = -\frac{49}{2} = -24\frac{1}{2}$
$-1\frac{7}{8} : 5 = -\frac{15}{8} : 5 = -\frac{3}{8}$
