Question

(4/17-7/20):(5/18+11/12)

làm nhanh giùm mình nha

 

Answer 1

\(\left(\dfrac{4}{17}-\dfrac{7}{20}\right):\left(\dfrac{5}{18}+\dfrac{11}{12}\right)\)

\(=\left(\dfrac{80}{340}-\dfrac{119}{340}\right):\left(\dfrac{10}{36}+\dfrac{33}{36}\right)\)

\(=\dfrac{-39}{340}:\dfrac{43}{36}\)

\(=\dfrac{-39}{340}.\dfrac{36}{43}\)

\(=\dfrac{-351}{3655}\)
