hk tốt

a: -10/8<-1

-19/19=-1

-1<-2/10<0

0<5/12<1<17/15

=>17/15>1>5/12>-2/10>-19/19>-10/8

b: -1/3=-4/12; -5/12=-5/12; -3/4=-9/12; -1/4=-3/12; -7/12=-7/12

=>-3/4<-7/12<-5/12<-1/3<-1/4

Theo thứ tự từ lớn đến bé:\(\dfrac{17}{15};1;\dfrac{5}{12};0;\dfrac{2}{-10};-\dfrac{19}{19};-\dfrac{10}{8}\)

Theo thứ tự từ bé đến lớn : \(-\dfrac{3}{4};-\dfrac{7}{12};-\dfrac{5}{12};-\dfrac{1}{3};\dfrac{1}{-4}\)

giải giúp mình mình cần gấp!!!

=> 5/6; 4/5; 2/3; 7/12; 1/2

                                1/2    ; 4/5    ; 2/3   ; 5/6     ; 7/12

Khi quy đồng ta có: 30/60; 48/60; 40/60; 50/60; 35/60

phân số có mẫu là `24` :

`-5/6=(-5xx4)/(6xx4)=-20/24`

`3/(-8) =-8/3=(-8xx8)/(3xx8)=-64/24`

`7/12=(7xx2)/(12xx2)=14/24`

`-25/100= -1/4= -6/24`

`72/108=2/3=16/24`

`10/60=1/6=4/24`

từ bé đến lớn là : `3/(-8) ; -5/6 ;-25/100; 10/60;72/108; 7/12`

-5/6=-20/24

-3/8=-9/24

7/12=14/24

-25/100=-1/4=-6/24

72/108=2/3=16/24

10/60=1/6=4/24

15/6; 2004/1999; 1;12/15;3/5

a, 9; 7; 5; 2

b, 1; 6; 4; 8

a) 9, 7, 5 2

b) 1, 4, 6, 8

a. 9-7-5-2

b. 1-4-6-8

\(\dfrac{12}{7};\dfrac{3}{2}\)

12/7 , 3/2

12 / 7 , 3 / 2

Ta có:
\(\dfrac{6}{5}=\dfrac{6\times168}{5\times168}=\dfrac{1008}{840}\)     ;    \(\dfrac{3}{4}=\dfrac{3\times210}{4\times210}=\dfrac{630}{840}\)     ;     \(\dfrac{9}{8}=\dfrac{9\times105}{8\times105}=\dfrac{945}{840}\) 

\(\dfrac{1}{7}=\dfrac{1\times120}{7\times120}=\dfrac{120}{840}\)     ;    \(\dfrac{2}{3}=\dfrac{2\times280}{3\times280}=\dfrac{560}{840}\)

⇒ \(\dfrac{120}{840}< \dfrac{560}{840}< \dfrac{630}{840}< \dfrac{945}{840}< \dfrac{1008}{840}\) ⇒ \(\dfrac{1}{7}< \dfrac{2}{3}< \)\(\dfrac{3}{4}< \dfrac{9}{8}< \dfrac{6}{5}\)
 

2/3 , 3/4 , 6/5 , 9/8 , 1/7 . 

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

\(\dfrac{8}{3};\dfrac{7}{7};\dfrac{6}{7};\dfrac{1}{2};\dfrac{3}{8}\)

\(\dfrac{8}{3}\);\(\dfrac{7}{7}\);\(\dfrac{6}{7}\);\(\dfrac{1}{2}\);\(\dfrac{3}{8}\)
