Answer 2

a) \((​​​​\dfrac{-1}{2})^{3}:\) I\(-1\dfrac{3}{8}\)I -25% .I\(-6\dfrac{2}{11}\)I . (-2)⁰

\(\dfrac{-1}{8}\) : \(\dfrac{11}{8}\) - \(\dfrac{1}{4}\) . \(\dfrac{68}{11}.1\)

\(\dfrac{-1}{11}-\dfrac{17}{11}=\dfrac{-18}{11}\)

b) \((\dfrac{-5}{9}:\dfrac{4}{11}+\dfrac{-4}{9}:\dfrac{4}{11}).\dfrac{8}{33}\)

\(\dfrac{11}{4}.(\dfrac{-5}{9}+\dfrac{-4}{9}).\dfrac{8}{33}\)

\(\dfrac{11}{4}.(-1).\dfrac{8}{33}\)

\(\dfrac{-2}{3}\)

c) \(\dfrac{-3}{7}.\dfrac{2}{11}+\dfrac{-3}{7}.\dfrac{9}{11}-1\dfrac{3}{7}\)

\(\dfrac{-3}{7}.(\dfrac{2}{11}+\dfrac{9}{11})-1\dfrac{3}{7}\)

\(\dfrac{-3}{7}.1-\dfrac{10}{7}\)

\(\dfrac{-13}{7}\)
