Answer 1

$1.\; 4)-3\frac{5}{9}*(-1\frac{1}{8})=\frac{3*9+5}{9}*\frac{1*8+1}{8}=\frac{32}{5}*\frac{9}{8}=\frac{4*9}{5}=\frac{36}{5}=7\frac{1}{5}=7,2\\\\\\2.\; b)\frac{5}{9}*(-3\frac{6}{7})-(-3\frac{5}{7})*\frac{3}{52}=-\frac{5}{9}*\frac{27}{7}+\frac{26}{7}*\frac{3}{52}=-\frac{5*3}{7}+\frac{3}{7*2}=-\frac{15}{7}+\frac{3}{14}=\\\\=-\frac{15*2}{14}+\frac{3}{14}=-\frac{30}{14}+\frac{3}{14}=-\frac{27}{14}=-1\frac{13}{14}$
