Question

Answer 1

\(=\dfrac{2}{5}\left(\dfrac{8}{5}-\dfrac{1}{3}-1\right)=\dfrac{2}{5}.\dfrac{4}{15}=\dfrac{8}{75}\)

Answer 2

\(\dfrac{8}{5}\) x \(\dfrac{2}{5}-\dfrac{2}{5}\) x \(\dfrac{1}{3}-\dfrac{2}{5}\)

\(=\dfrac{2}{5}\) x \(\left(\dfrac{8}{5}-\dfrac{1}{3}-1\right)\)

\(=\dfrac{2}{5}\) x \(\left(\dfrac{24}{15}-\dfrac{5}{15}-\dfrac{15}{15}\right)\)

\(=\dfrac{2}{5}\) x \(\dfrac{4}{15}\)

\(=\dfrac{8}{75}\)
