Answer 1

$frac{(3frac{7}{11}-5cdot2 frac{7}{22})cdot0.08+1:1frac{4}{7}}{2frac{1}{3}:frac{4}{9}-15.4cdot0.18}= frac{(frac{40}{11}-5cdot frac{51}{22})cdotfrac{8}{100}+1: frac{11}{7}}{ frac{7}{3}cdot frac{9}{4}-2.772} = frac{(frac{80}{22}-frac{255}{22})cdot frac{8}{100} + frac{7}{11}}{ frac{21}{4}-2.772 } = \ =frac{-frac{175}{22}cdot frac{8}{100} + frac{7}{11}}{ 5.25-2.772 } = frac{-frac{175}{275} + frac{175}{275}}{2.478 } =frac{0}{2.478 } =0$
