[Lợi Trần]

\((3-\dfrac{7}{3}+\dfrac{1}{4}\))\(\div\)\(\left(4-\dfrac{31}{6}+\dfrac{9}{4}\right)\)=

\(\left(\dfrac{36}{12}-\dfrac{28}{12}+\dfrac{3}{12}\right)\div\left(\dfrac{48}{12}-\dfrac{62}{12}+\dfrac{27}{12}\right)\)=

\(\dfrac{11}{12}\div\dfrac{13}{12}\)=\(\dfrac{11}{12}\times\dfrac{12}{13}=\dfrac{11}{13}\)
