Question

-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 можно без решения

Answer 1

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

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

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

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

Удачи))))
