Answer 1

$(1frac{1}{12}+1frac{1}{4})*1frac{19}{56}+2frac{5}{8}*1frac{3}{7}*1frac{1}{9} =(frac{13}{12}+frac{5}{4})* frac{75}{56}+frac{21}{8}*frac{10}{7}*frac{10}{9}=$$(frac{13}{12}+frac{5*3}{4*3})* frac{75}{56}+frac{7*3}{2*4}*frac{2*5}{7}*frac{2*5}{3*3}=frac{13+15}{12}*frac{75}{56}+frac{25}{6}=frac{28}{12}*frac{75}{56}+frac{25}{6}=$$frac{2*14}{3*4}*frac{75}{4*14}+frac{25}{6} =frac{25}{8}+frac{25}{6}= frac{25*3+25*4}{24} = frac{75+100}{24}= frac{175}{24}=7 frac{7}{24}$
