Sắp xếp các phân số sau theo thứ tự tăng dần :

\(\dfrac{1}{2}\);\(\dfrac{2}{3}\);\(\dfrac{3}{4}\);\(\dfrac{4}{5}\);\(\dfrac{5}{6}\);\(\dfrac{6}{7}\);\(\dfrac{7}{8}\);\(\dfrac{8}{9}\);\(\dfrac{9}{10}\)

\(=>\dfrac{1}{6}< \dfrac{2}{3}< \dfrac{5}{5}< \dfrac{5}{4}< \dfrac{19}{12}\)

a,\(\dfrac{1}{6},\dfrac{2}{3},\dfrac{5}{5},\dfrac{5}{4},\dfrac{19}{12}\)

b,\(\dfrac{8}{11}\)\(x=\dfrac{1}{5}\)

\(x=\dfrac{1}{5}:\dfrac{8}{11}\)

\(x=\dfrac{11}{40}\)

\(\dfrac{8}{11}xX=\dfrac{1}{5}=>X=\dfrac{1}{5}:\dfrac{8}{11}=>X=\dfrac{11}{40}\)

a) 1/2
b) 18/17; 17/16; 16/15; 15/14; 14/13; 13/12; 10/9
Nhớ k cho mk nha

a)1/2

b)Vì 18/17 <17/16 <16/15<15/14< 14/13< 13/12< 10/9

Nên, ta có: 

18/17; 17/16; 16/15; 15/14; 14/13; 13/12; 10/9.

1/2 < 2/3 < 3/4 <4/5 < 5/6 <6/7 <7/8 <8/9 < 9/10 

Sắp xép theo thứ tự giảm dần là :

      9/10 ; 8/9 ; 7/8 ; 6/7 ; 5/6 ; 4/5; 3/4 ; 2/3 ; 1/2

9/10,8/9,7/8,6/7,5/6,4/5,3/4,2/3,1/2

9/10,8/9,7/8,6/7,5/6,4/5,3/4,2/3,1/2

a) \(\dfrac{-25}{19}< \dfrac{-13}{19}< \dfrac{9}{19}< \dfrac{14}{19}< \dfrac{20}{19}< \dfrac{30}{19}< \dfrac{42}{19}\)

b) \(\dfrac{-2}{15}< \dfrac{-1}{10}< \dfrac{1}{6}< \dfrac{1}{5}< \dfrac{4}{15}< \dfrac{1}{3}< \dfrac{2}{5}\)

9/10>8/9>7/8>6/7>5/6>4/5>3/4>2/3>1/2

a)\(\dfrac{-5}{6};\dfrac{-3}{4};\dfrac{7}{24};\dfrac{2}{3};\dfrac{7}{8};\dfrac{16}{17}\)

b)\(\dfrac{20}{23};\dfrac{205}{107};\dfrac{214}{315};\dfrac{7}{10};\dfrac{-5}{8};\dfrac{-16}{19}\)
