Question

Answer 1

\(=\dfrac{9}{20}\cdot\dfrac{-2}{5}+\left(\dfrac{11}{2}-\dfrac{4}{3}\right):\dfrac{-5}{3}+\dfrac{-1}{8}+\dfrac{-1}{8}\)

\(=\dfrac{-9}{20}+\dfrac{25}{6}\cdot\dfrac{-3}{5}+\dfrac{-1}{4}\)

\(=\dfrac{-9-5}{20}+\dfrac{-5}{2}=\dfrac{-14}{20}+\dfrac{-50}{20}=\dfrac{-64}{20}=-\dfrac{16}{5}\)

Answer 2

\(=\dfrac{9}{20}.\dfrac{-2}{5}+\dfrac{31}{6}:\dfrac{-5}{3}+\dfrac{-1}{8}+\dfrac{-1}{8}\)

\(=\dfrac{-9}{50}+\dfrac{-31}{10}+\dfrac{-1}{8}+\dfrac{-1}{8}\)

\(=\dfrac{-353}{100}\)
