Question

1. в) 8 целых 6/23*7/13+6/13*8 целых 6/13 г)(4/7: 8/19)*1 целых 3/4 2. б) x * 5/6 =5/33 в)1 целых 6/7 * x=9/24

Answer 1

$8\frac{6}{13} ( \frac{7}{13} + \frac{6}{13} ) = 8\frac{6}{13} * \frac{13}{13} = 8\frac{6}{13}$

$( \frac{4}{7} : \frac{8}{19} ) * 1 \frac{3}{4} = \frac{19}{8} = 2 \frac{3}{8}$

$\frac{5}{6} x = \frac{5}{33} \\ \\ x = \frac{5}{33}: \frac{5}{6} \\ \\ x = \frac{5}{33}* \frac{6}{5} \\ \\ x= \frac{2}{11}$

$1 \frac{6}{7} x= \frac{9}{24} \\ \\ \frac{13}{7} x= \frac{9}{24} \\ \\ \ x= \frac{9}{24} : \frac{13}{7} \\ \\ \ x= \frac{9}{24} * \frac{7}{13} \\ \\ x= \frac{21}{104}$
