Answer 1

$2 frac{3}{4}/((4 frac{5}{12}-1 frac{11}{14})*4 frac{2}{3}+(3 frac{2}{9}-1 frac{5}{6})* frac{18}{25})= frac{99}{486}$


$4 frac{5}{12}-1 frac{11}{14}= 4 frac{35}{84}-1 frac{66}{84}=3 frac{119}{84}-1 frac{66}{84}=2 frac{53}{84}$

$3 frac{2}{9}-1 frac{5}{6}= 3 frac{4}{18}-1 frac{15}{18}= 2 frac{22}{18}-1 frac{15}{18}=1 frac{7}{18}$

$2 frac{53}{84}*4 frac{2}{3}=frac{221*14}{84*3}= frac{221}{18}=12 frac{5}{18}$

$1 frac{7}{18}* frac{18}{25}= frac{25*18}{18*25}=1$

$12 frac{5}{18}+1=13 frac{5}{18}$

$2 frac{3}{4}/ 13 frac{5}{18}= frac{11*18}{4*239}= frac{99}{486}$
