(4 5/9-3 7/12):(-1 8/27

Answer 1

1)$(-1,56-1,24)*(-1\frac{5}{14})=(-1\frac{56}{100}-1\frac{24}{100})*(-\frac{19}{5})=-\frac{280}{100}*(-\frac{19}{5})=\frac{56*19}{100}=\frac{14*19}{25}=10\frac{16}{25}$

2)$(4\frac{5}{9}-3\frac{7}{12} ):(-1\frac{8}{27})=(4\frac{20}{36} -3\frac{21}{36})*(-\frac{27}{35} )=\frac{15}{36}*(-\frac{27}{35}) =\frac{3}{4} *(-\frac{3}{7} )=-\frac{9}{28}$
