-27/20*(-5/9)-5/24*(-22/5) 29/30*5/18*6/25 2/7+3/8:7/32 18/7*(4/9+15/18) Срочно надо...

$= \frac{3}{4} + \frac{1}{12} \times 11 = \frac{3}{4} + \frac{11}{12} = \frac{5}{3} = 1 \frac{2}{3} \\ \\ \\ \\$

$= \frac{29}{6} \times \frac{1}{3} \times \frac{1}{25} = \frac{29}{450}$

$= \frac{2}{7} + \frac{3}{8} \times \frac{32}{7} = \frac{2}{7} + 3 \times \frac{4}{7} = \frac{2}{7} + \frac{12}{7} = 2$

$= \frac{18}{7} \times \frac{23}{18} = \frac{1}{7} \times 23 = \frac{23}{7} = 3 \frac{2}{7}$

Удачи))))
