Question

Answer 1

k: \(=\dfrac{5}{7}\cdot\dfrac{8}{17}-\dfrac{5}{7}\cdot\dfrac{25}{17}=\dfrac{5}{7}\left(\dfrac{8}{17}-\dfrac{25}{17}\right)=-\dfrac{5}{7}\)

g: \(=\dfrac{-15}{19}\cdot\dfrac{19}{5}\cdot\dfrac{3}{11}\cdot\left(-33\right)=-3\cdot\left(-33\right)\cdot\dfrac{3}{11}=99\cdot\dfrac{3}{11}=27\)

h: \(=\dfrac{4}{9}\left(\dfrac{-5}{13}-\dfrac{11}{13}+\dfrac{3}{13}\right)=\dfrac{4}{9}\cdot\left(-1\right)=-\dfrac{4}{9}\)
