                        MỌI NGƯỜI GIẢI HỘ EM VỚI

 

Answer 1

\(\left(\dfrac{5}{11}+\dfrac{3}{11}\right):\dfrac{3}{4}=\dfrac{8}{11}:\dfrac{3}{4}=\dfrac{8}{11}\times\dfrac{4}{3}=\dfrac{32}{33}\)

Answer 2

\(C1:=\dfrac{8}{11}\times\dfrac{4}{3}=\dfrac{32}{33}\)

\(C2:=\dfrac{5}{11}\times\dfrac{4}{3}+\dfrac{3}{11}\times\dfrac{4}{3}=\dfrac{20}{33}+\dfrac{12}{33}=\dfrac{32}{33}\)

Answer 3

\(C_2:\left(\dfrac{5}{11}+\dfrac{3}{11}\right):\dfrac{3}{4}=\dfrac{5}{11}:\dfrac{3}{4}+\dfrac{3}{11}:\dfrac{3}{4}=\dfrac{5}{11}\times\dfrac{4}{3}+\dfrac{3}{11}\times\dfrac{4}{3}=\dfrac{20}{33}+\dfrac{12}{33}=\dfrac{32}{33}\)
