$\displaystyle 1). \ \ \frac{7}{8}*1\frac{5}{7}+\frac{2}{9}*2,7=\frac{7}{8}*\frac{12}{7}+\frac{2}{9}*\frac{27}{10}=1,5+0,6=2,1;\\\\\\2). \ \ 4,6+\bigg(5,4+3\frac{2}{3}\bigg)*\frac{3}{8}=4,6+\bigg(\frac{54}{10}+\frac{11}{3}\bigg)*\frac{3}{8}=\\\\\\=4,6+\frac{162+110}{30}*\frac{3}{8}=4,6+\frac{272}{10*8}=4,6+3,4=8;\\\\\\3). \ \ -9+\frac{1}{3}+\frac{2}{5}=-9+\frac{5+6}{15}=-8\frac{4}{15};$

$\displaystyle 4). \ \ -2\frac{1}{7}:4\frac{1}{6}:\bigg(-\frac{3}{7}\bigg)=\frac{15}{7}:\frac{25}{6}:\frac{3}{7}=\frac{15}{7}*\frac{6}{25}*\frac{7}{3}=1,2;\\\\\\5). \ \ -42+14+25-65+1=-42+15-40=-42-25=-67;$
