Ответ:

$\displaystyle(1\frac{1}{9} *1\frac{1}{5} +1-\frac{1}{9} ):(8\frac{5}{9} *\frac{3}{14} -\frac{7}{18}) =1\frac{7}{13}$

$1)\displaystyle1\frac{1}{9} *1\frac{1}{5}=\frac{10}{9} *\frac{6}{5} =\frac{2*2}{3*1} =\frac{4}{3}$

$2)\displaystyle\frac{4}{3} +1=\frac{4}{3} +\frac{3}{3} =\frac{7}{3}$

$3)\displaystyle\frac{7}{3} -\frac{1}{9} =\frac{21}{9} -\frac{1}{9} =\frac{20}{9}$

$4)\displaystyle8\frac{5}{9} *\frac{3}{14} =\frac{77}{9} *\frac{3}{14} =\frac{11*1}{3*2} =\frac{11}{6}$

$5)\displaystyle\frac{11}{6} -\frac{7}{18} =\frac{33}{18} -\frac{7}{18} =\frac{26}{18}$

$6)\displaystyle\frac{20}{9} :\frac{26}{18} =\frac{20}{9} *\frac{18}{26} =\frac{20*2}{1*26} =\frac{40}{26}=\frac{20}{13} =1\frac{7}{13}$
