Answer 2

I can help you with some math problems. Here are the solutions:

- $(\frac{8}{11}+\frac{3}{22}):\frac{5}{11}=\frac{22}{55}:\frac{5}{11}=\frac{22}{55}\cdot\frac{11}{5}=\frac{22}{5}\cdot\frac{1}{11}=\frac{4}{1}=\mathbf{4}$ - $1+\frac{7}{12}:(\frac{3}{8}+\frac{5}{12})=1+\frac{7}{12}:\frac{9}{8}=1+\frac{7}{12}\cdot\frac{8}{9}=1+\frac{56}{108}=1+\frac{28}{54}=1+\frac{14}{27}=\frac{27}{27}+\frac{14}{27}=\frac{41}{27}=\mathbf{\frac{41}{27}}$ - $\frac{17}{36}:(\frac{7}{12}-\frac{5}{9})=\frac{17}{36}:(\frac{21}{36}-\frac{20}{36})=\frac{17}{36}:\frac{1}{36}=\frac{17}{36}\cdot\frac{36}{1}=\frac{17}{1}=\mathbf{17}$ - $(\frac{3}{14}+\frac{5}{7}):(\frac{3}{5}+\frac{7}{5})=(\frac{3}{14}+\frac{10}{14}):(\frac{10}{5})=(\frac{13}{14}):\frac{10}{5}=\frac{13}{14}\cdot\frac{5}{10}=\frac{13}{28}=\mathbf{\frac{13}{28}}$ - $\frac{19}{24}:(\frac{3}{16}+\frac{5}{25})=\frac{19}{24}:(\frac{75}{400}+\frac{64}{400})=\frac{19}{24}:\frac{139}{400}=\frac{19}{24}\cdot\frac{400}{139}=\frac{7600}{3336}=\frac{1900}{834}=\mathbf{\frac{1900}{834}}$Ответь+подробно.+Выполните+дествия+:+(+8/11+3/22):5/11;+1+7/12:(3/8+5/12);+17/36:(7/12-5/9);+(3/14+5/7):3+5/7;+19/24:(3/16+5/25).
