Answer 1

\(\frac{-1}{3}+\frac{0,2-0,375+\frac{5}{11}}{-\frac{3}{10}+\frac{9}{16}-\frac{15}{22}}\)

\(=\frac{-1}{3}+\frac{\frac{2}{10}-\frac{3}{8}+\frac{5}{11}}{-\frac{3}{10}+\frac{9}{16}-\frac{15}{22}}\)

\(=\frac{-1}{3}+\frac{\frac{2}{10}-\frac{3}{8}+\frac{5}{11}}{-\frac{3}{2}.\left(\frac{2}{10}-\frac{3}{8}+\frac{5}{11}\right)}\)

\(=\frac{-1}{3}+\frac{1}{-\frac{3}{2}}\)

\(=\frac{-1}{3}+\frac{-2}{3}=-\frac{3}{3}=-1\)
