frac{4}{3} +frac{1}{8}:frac{5}{11} =frac{4}{3} +frac{1*11}{8*5}=frac{4}{3} +frac{11} {40} = 1frac{160}{120} +frac{33}{120} = 1frac{53}{120} .\\frac{6}{2}*frac{1}{4}:frac{3}{5}=3*frac{5}{3}*frac{1}{4} = 5*frac{1}{4}=1frac{1}{4} .\\frac{1}{7}*frac{2}{3} - frac{4}{5} :frac{1}{2}=frac{2}{21} - frac{8}{5} = frac{10-168}{105}= -1frac{158}{105}. \\

frac{1}{6} -frac{2}{7} : frac{3}{8}+frac{4}{5}= frac{1}{6} -frac{16}{21}+frac{4}{5} =frac{7}{42} -frac{32}{42}+frac{4}{5} = -frac{25}{42}+frac{4}{5} = frac{-125 +168}{210} = frac{43}{210}
