\(\dfrac{3}{4}\) = \(\dfrac{3\times3}{4\times3}\) = \(\dfrac{9}{12}\)
\(\dfrac{2}{3}\) = \(\dfrac{2\times4}{3\times4}\) = \(\dfrac{8}{12}\)
\(\dfrac{5}{6}\) = \(\dfrac{5\times2}{6\times2}\) = \(\dfrac{10}{12}\)
Vì \(\dfrac{8}{12}< \dfrac{9}{12}< \dfrac{10}{12}< \dfrac{11}{12}\)
Vậy phân số lớn nhất là: \(\dfrac{11}{12}\)
Phân số bé nhất là: \(\dfrac{2}{3}\)
