Ответ:

$1)1\frac{18}{55}$

$2)5\frac{1}{16}$

Пошаговое объяснение:

$1)1\frac{3}{5} -\frac{8}{7} *(\frac{15}{24} -\frac{13}{32} )*\frac{12}{11} =1\frac{3}{5} -\frac{8}{7} *\frac{7}{32}*\frac{12}{11} =1\frac{3}{5}-\frac{8}{7} *\frac{21}{88} =1\frac{3}{5} -\frac{3}{11} =1\frac{18}{55} =1,3272727272727272$

$2)3\frac{1}{9} :2\frac{1}{3} :6\frac{3}{4} *\frac{9}{16} =3\frac{1}{9} :\frac{28}{81} *\frac{9}{16} =9*\frac{9}{16} =5\frac{1}{16} =5,0625$
