Question

помогите решить пример под цифрой 2

Answer 1

$m+(-2frac{4}{9})+8frac{13}{24}+n+(-3frac{2}{9})+(-4frac{5}{24})=$$m-2frac{4}{9}+frac{205}{24}+n+-3frac{2}{9}-4frac{5}{24}=m-frac{22}{9}+frac{205}{24}+n+-frac{29}{9}-frac{101}{24}=$$m+ frac{-176+615-232-303}{72}+n=m-frac{96}{72}+n=m-frac{4}{3}+n$
$-3frac{5}{6}-frac{4}{3}-2frac{11}{12}=-frac{23}{6}-frac{4}{3}-frac{35}{12}=- frac{46+16+35}{12}=-frac{97}{12}=-8frac{1}{12}$
