Question

D = \(\frac{-1}{5}\) .  \(\left(\frac{9}{8}+\frac{16}{32}-\frac{12}{46}\right)-\frac{9}{17}\)

Answer 1

\(D=\frac{-1}{5}.\left(\frac{9}{8}+\frac{16}{32}-\frac{12}{46}\right)-\frac{9}{17}\)

\(D=\frac{-1}{5}.\frac{251}{184}+\frac{-9}{17}\)

\(D=\frac{-251}{920}+\frac{-9}{17}\)

\(D=\frac{-12547}{15640}\)

Answer 2

\(D=\frac{-1}{5}\cdot\left[\frac{9}{8}+\frac{16}{32}+\frac{12}{46}\right]-\frac{9}{17}\)

\(D=\frac{-1}{5}\cdot\left[\frac{9}{8}+\frac{1}{2}-\frac{6}{23}\right]-\frac{9}{17}\)

\(D=\frac{-1}{5}\cdot\left[\frac{9}{8}+\frac{4}{8}-\frac{6}{23}\right]-\frac{9}{17}\)

\(D=\frac{-1}{5}\cdot\left[\frac{15}{8}-\frac{6}{23}\right]-\frac{9}{17}\)

\(D=\frac{-1}{5}\cdot\left[\frac{345}{184}-\frac{48}{184}\right]-\frac{9}{17}\)

\(D=\frac{-1}{5}\cdot\frac{297}{184}-\frac{9}{17}\)
