Answer 1

( 1 )

$-16*3-24= -48-24=-72$

( 2 )

$\frac{3}{16}*(\frac{4}{5}-\frac{8}{15})=\frac{3}{16}*(\frac{12}{15}-\frac{8}{15})= \frac{3}{16}*\frac{4}{15}=\frac{1}{4}*\frac{1}{5}=\frac{1}{20}=0,05$

( 3 )

$9,3-11,4:1,5=9,3-7,6=1,7$

( 5 )

A = $\frac{3}{17}$

B =  $\frac{17}{15}=1\frac{2}{15}$

C =  $\frac{17}{8} =2\frac{1}{8}$

( 6 )

$4\frac{10}{11}*(\frac{8}{9}-\frac{7}{12})-9:2\frac{4}{7}=\frac{54}{11}*(\frac{32}{36}-\frac{21}{36})-9:2\frac{4}{7}=\frac{54}{11}*\frac{11}{36}-9:\frac{18}{7}=\\\\=\frac{9}{1}*\frac{1}{6}-9:\frac{18}{7}=\frac{9}{6}-\frac{9}{1} *\frac{7}{18}=\frac{3}{2}-\frac{1}{1} *\frac{7}{2}=\frac{3}{2}-\frac{7}{2}=-\frac{4}{2}=-2$
