Question

Sắp xếp thứ tự tăng dần: 1/2, 2/3, 5/6, 7/12

Answer 1

1/2 ; 2/3 ; 5/6 ; 7/12

Answer 2

\(\dfrac{1}{2};\dfrac{7}{21};\dfrac{2}{3};\dfrac{5}{6}\)

Answer 3

\(\dfrac{1}{2}=\dfrac{6}{12};\dfrac{2}{3}=\dfrac{8}{12};\dfrac{5}{6}=\dfrac{10}{12};\dfrac{7}{12}\\ \Rightarrow\dfrac{6}{12}< \dfrac{7}{12}< \dfrac{8}{12}< \dfrac{10}{12}\\ \Rightarrow\dfrac{1}{2}< \dfrac{7}{12}< \dfrac{2}{3}< \dfrac{5}{6}\)
