Question

помогите решить примеры

Answer 1

$frac{(4,5cdot 1frac{2}{3}-6,75)cdot frac{2}{3}}{(3frac{1}{3}cdot 0,3+5frac{1}{3}cdot frac{1}{8}):2frac{2}{3}}+ frac{1frac{4}{11}cdot 0,22:0,3-0,96}{(0,2-frac{3}{40})cdot 1,6} =\\= frac{(frac{9}{2}cdot frac{5}{3}-frac{27}{4})cdot frac{2}{3}}{(frac{10}{3}cdot frac{3}{10}+frac{16}{3}cdot frac{1}{8}):frac{8}{3}} + frac{frac{15}{11}cdot frac{11}{50}:frac{3}{10}-frac{48}{50}}{(frac{1}{5}-frac{3}{40})cdot frac{8}{5}}=$

$= frac{(frac{15}{2}-frac{27}{4})cdot frac{2}{3}}{(1+frac{2}{3})cdot frac{3}{8}} + frac{frac{3}{25}cdot frac{10}{3}-frac{24}{25}}{frac{5}{40}cdot frac{8}{5}} = frac{frac{3}{4}cdot frac{2}{3}}{frac{5}{3}cdot frac{3}{8}} +frac{frac{10}{25}-frac{24}{25}}{frac{8}{40}} =\\= frac{frac{1}{2}}{frac{5}{8}} + frac{-frac{14}{25}}{frac{1}{5}} = frac{8}{2cdot 5} - frac{14cdot 5}{25} = frac{4}{5} - frac{14}{5} =-frac{10}{5}=-2$
