помогите пожалуйста!​

Answer 1

Відповідь:

$5\frac{5}{7} :2\frac{2}{5}*5\frac{1}{4}:1\frac{1}{6}*\frac{2}{3} =\frac{40}{7} *\frac{5}{12} *\frac{21}{4}*\frac{6}{7} *\frac{2}{3}=\frac{5*5*1*1*2}{7*1*1*1*1} =\frac{50}{7} =7\frac{1}{7}$

$1\frac{8}{17}*3\frac{2}{5}:\frac{11}{12}*2\frac{1}{5}:\frac{4}{9}=\frac{25*17*12*11*9}{17*5*11*5*4} =\frac{1*1*3*1*9}{1*1*1*1*1}=3*9=27$
