a: Ta có: -97<-72<-36<-15<-7<-2

=>\(\frac{-97}{24}<\frac{-72}{24}<\frac{-36}{24}<-\frac{15}{24}<-\frac{7}{24}<-\frac{2}{24}\)

b: Ta có: \(\frac{-3}{5}=\frac{-3\cdot4}{5\cdot4}=\frac{-12}{20}\)

\(\frac{1}{-5}=\frac{-1}{5}=\frac{-1\cdot4}{5\cdot4}=\frac{-4}{20}\)

\(\frac{-3}{4}=\frac{-3\cdot5}{4\cdot5}=\frac{-15}{20}\)

mà -4>-12>-15

nên \(\frac{1}{-5}>\frac{-3}{5}>-\frac34\)

=>\(\frac{1}{-5}>\frac{-3}{5}>\frac{-3}{4}>-1\left(1\right)\)

Ta có: \(-1=\frac{-12}{12};\frac{5}{-3}=\frac{-5}{3}=\frac{-5\cdot4}{3\cdot4}=\frac{-20}{12};\frac{5}{-4}=\frac{-5}{4}=\frac{-5\cdot3}{4\cdot3}=\frac{-15}{12}\)

mà -12>-15>-20

nên \(-1>\frac{-5}{4}>-\frac53\) (2)

Từ (1),(2) suy ra \(\frac{1}{-5}>\frac{-3}{5}>\frac{-3}{4}>\frac{-5}{4}>-\frac53\)

trả lời giúp mình nha! mình sẽ cho  ^^

\(a\)) \(-17;-2;0;1;2;5\)

\(b\))\(2001;15;7;0;-8;-101\)

a) -17, -2, 0, 1, 2, 5. b) 2001, 15, 7, 0, -8, -101.

-5/9;-1/3;-1/2;1/3;5/12;7/18

- 5/9 <  -1/3 < - 1/2 < 1/3 < 7/18 < 5/12

Học tốt!

Giải:

a)

\(\dfrac{7}{48}=\dfrac{105}{720};\)

\(\dfrac{11}{72}=\dfrac{110}{720};\)

\(\dfrac{17}{120}=\dfrac{102}{720}\)

Vì \(102< 105< 110\)

\(\Leftrightarrow\dfrac{102}{720}< \dfrac{105}{720}< \dfrac{110}{720}\)

\(\Leftrightarrow\dfrac{17}{120}< \dfrac{7}{48}< \dfrac{11}{72}\)

Vậy ...

b) \(\dfrac{31}{49}=\dfrac{60140}{95060};\)

\(\dfrac{62}{97}=\dfrac{60760}{95060};\)

\(\dfrac{93}{140}=\dfrac{63147}{95060}\)

Vì \(60140< 60760< 63147\)

\(\Leftrightarrow\dfrac{60140}{95060}< \dfrac{60760}{95060}< \dfrac{63147}{95060}\)

\(\Leftrightarrow\dfrac{31}{49}< \dfrac{62}{97}< \dfrac{93}{140}\)

Vậy ...

a ) \(\dfrac{7}{48}\) = \(\dfrac{105}{720}\)

\(\dfrac{11}{72}\) = \(\dfrac{110}{720}\)

\(\dfrac{17}{120}\) = \(\dfrac{102}{720}\)

Vì 102 < 105 < 110

\(\Leftrightarrow\) \(\dfrac{102}{720}\) < \(\dfrac{105}{720}\) < \(\dfrac{110}{720}\)

\(\Leftrightarrow\) \(\dfrac{17}{120}\) < \(\dfrac{7}{48}\) < \(\dfrac{11}{72}\)

Vậy .....................

( k cho tớ nha . Tớ chỉ bt lm phần a )

9/16:9/8 ; 5/7:6/7; 105/22:35/11 ;  3/5:7/10

nhớ k cho mình nha

\(-1,6<-\frac{18}{12}<\frac{10}{-7}\)

Ta sắp xếp theo thứ tự tăng dần là:\(-1,6;\frac{-18}{12};\frac{10}{-7}\)

\(\frac{-5}{6}< \frac{-3}{4}< \frac{7}{24}< \frac{2}{3}< \frac{7}{8}\)
