Question

mọi người giúp mình với ạ

Answer 1

a: \(=\dfrac{-9}{13}\left(\dfrac{12}{29}+\dfrac{17}{29}\right)+1+\dfrac{11}{13}=\dfrac{-9}{13}+\dfrac{11}{13}+1=1+\dfrac{2}{13}=\dfrac{15}{13}\)

b: \(=\left(\dfrac{5}{3}-\dfrac{2}{11}\right):\dfrac{49}{33}+\dfrac{4}{49}-\dfrac{1}{14}\)

\(=\dfrac{49}{33}\cdot\dfrac{33}{49}+\dfrac{8-7}{98}=\dfrac{99}{98}\)
