\(a,-\dfrac{3}{2};-\dfrac{2}{3};0;\dfrac{4}{7};\dfrac{2}{3}\\ b,\dfrac{4}{3};\dfrac{4}{5};0,2;-\dfrac{5}{2}\)

9/24,7/12,5/6,23/24

Sắp xếp p/s theo thứ tự tăng dần :

9/24 ,  7/12  , 5/6   , 23/24

Chúc bn hk tốt !

9/24 -> 7/12-> 5/6 -> 23/24 

Li ke nhé . Thanks

Quy đồng các phân số đã cho lên, ta được:

\(\dfrac{3}{4}=\dfrac{3\times42}{4\times42}=\dfrac{126}{168}\)

\(\dfrac{5}{6}=\dfrac{5\times28}{6\times28}=\dfrac{140}{168}\)

\(\dfrac{11}{8}=\dfrac{11\times21}{8\times21}=\dfrac{231}{168}\)

\(\dfrac{8}{7}=\dfrac{8\times24}{7\times24}=\dfrac{192}{168}\)

\(5=\dfrac{5}{1}=\dfrac{5\times168}{1\times168}=\dfrac{840}{168}\)

Mà \(\dfrac{840}{168}>\dfrac{231}{168}>\dfrac{192}{168}>\dfrac{140}{168}>\dfrac{126}{168}\)

Vậy ta sắp xếp được các phân số theo thứ tự tăng dần là: \(\dfrac{3}{4};\dfrac{5}{6};\dfrac{8}{7};\dfrac{11}{8};5\).

`3/4 ; 5/6 ; 8/7 ; 11/8 ; 5`

`#` `\text{dkhanhqlv}`

Ta có :

`3/4<1`

`5/6<1`

`11/8>1`

`8/7>1`

`5>1`

`11/8=385/280`

`8/7=320/280`

`5=1400/280`

`=>3/4<5/6<8/7<11/8<5`

MSC : `24`

`-5/6=-5.4/6.4=-20/24`

`7/8=7.3/8.3=21/24`

`7/24=7/24`

`-3/4=-3.6/4.6=-18/24`

`2/3=2.8/3.8=16/24`

`1=24/24`

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

`-20/24;-18/24;7/24;16/24;21/24;24/24`

1/2;3/5;3/4;5/3

1/2; 3/5; 3/4; 5/3

1/2;2/3;3/4;5/3

\(\dfrac{3}{4}=\dfrac{3\times5}{4\times5}=\dfrac{15}{20}\)

\(\dfrac{2}{4}=\dfrac{2\times5}{4\times5}=\dfrac{10}{20}\)

\(1=\dfrac{20}{20}\)

\(\dfrac{6}{5}=\dfrac{6\times4}{5\times4}=\dfrac{24}{20}\)

Vì \(\dfrac{10}{20}< \dfrac{15}{20}< \dfrac{20}{20}< \dfrac{24}{20}\) nên \(\dfrac{2}{4}< \dfrac{3}{4}< 1< \dfrac{6}{5}\)
