Question

xắp xếp theo thứ thứ tự từ bé đến lớn

5/6; 7/8; 7/24; 16/17; 3/4; 2/3; 9/54 

giải kĩ giúp mình với ạ

Answer 1

\(\dfrac{9}{54}=\dfrac{1}{6}=\dfrac{4}{24}< \dfrac{7}{24}\)

\(\dfrac{7}{24}< \dfrac{12}{24}< \dfrac{16}{24}=\dfrac{2}{3}\)

\(\dfrac{2}{3}< \dfrac{2+1}{3+1}=\dfrac{3}{4}\)

\(\dfrac{3}{4}< \dfrac{3+2}{4+2}=\dfrac{5}{6}\)

\(\dfrac{5}{6}< \dfrac{5+2}{6+2}=\dfrac{7}{8}\)

\(\dfrac{7}{8}< \dfrac{7+9}{8+9}=\dfrac{16}{17}\)

Vậy \(\dfrac{9}{54}< \dfrac{7}{24}< \dfrac{2}{3}< \dfrac{3}{4}< \dfrac{5}{6}< \dfrac{7}{8}< \dfrac{16}{17}\)
