= ( 1/3+ 4/3+2/3)+ ( 1/6+ 2/6+ 5/6)
= 7/3+ 4/3
= 11/3
11/3 nha bạn ( nhưng chưa chắc )
\(\dfrac{1}{3}+\dfrac{1}{6}+\dfrac{4}{3}+\dfrac{2}{6}+\dfrac{5}{6}\)
\(=\left(\dfrac{1}{3}+\dfrac{2}{3}+\dfrac{4}{3}\right)+\left(\dfrac{1}{6}+\dfrac{2}{6}+\dfrac{5}{6}\right)\)
\(=\dfrac{7}{3}+\dfrac{8}{6}\)
\(=\dfrac{14}{6}+\dfrac{8}{6}\) \(=\dfrac{22}{6}=\dfrac{11}{3}\)
