 Числитель:

$((3 frac{7}{12}-2 frac{11}{18}+2 frac{1}{24})*1 frac{5}{31}- frac{3}{52}*(3 frac{1}{2}+ frac{5}{6}))*1 frac{7}{13}=$$((3 frac{42}{72}-2 frac{44}{72}+2 frac{3}{72})*frac{36}{31}- frac{3}{52}*(3 frac{3}{6}+ frac{5}{6}))* frac{20}{13}=$ = $(3 frac{1}{72}* frac{36}{31}- frac{3}{52}*4 frac{2}{6})* frac{20}{13}= (frac{217}{72}* frac{36}{31}- frac{3}{52}* frac{26}{6})* frac{20}{13}= ( frac{7}{2}- frac{1}{4}* frac{20}{13}) =$ $frac{13}{4}* frac{20}{13}=5$

Знаменатель:

$frac{19}{84} / (5 frac{52}{168}-2 frac{78}{168}+ frac{35}{168})+1 frac{2}{27}- frac{4}{27}= frac{19}{84} / 3 frac{9}{168}+1 frac{2}{27}- frac{4}{27}=$$frac{19}{84} / frac{513}{168} + 1 frac{2}{27}- frac{4}{27}= frac{19}{84} * frac{168}{513} + 1 frac{2}{27} - frac{4}{27} = frac{2}{27} + 1 frac{2}{27} - frac{4}{27} = 1$

Действие дроби:

5 / 1 = 5
