Question

Answer 1

d: \(=\dfrac{-5+18-14}{24}\cdot\dfrac{-16}{5}\)

\(=\dfrac{-1}{24}\cdot\dfrac{-16}{5}=\dfrac{16}{120}=\dfrac{2}{15}\)

e: \(=\dfrac{-5}{7}\left(\dfrac{2}{11}+\dfrac{9}{11}\right)=\dfrac{-5}{7}\)

g: \(=\dfrac{6}{7}-\dfrac{1}{4}+\dfrac{1}{28}\cdot4\)

=1-1/4=3/4

Answer 2

D: \(\dfrac{2}{15}\) ;E: \(\dfrac{-5}{7}\); G:\(\dfrac{3}{4}\)

Answer 3

=67−14+128⋅4=67−14+128⋅4

=1-1/4=3/4
