a: \(-\dfrac{11}{33}< 0< \dfrac{25}{16}\)

b: \(-\dfrac{17}{23}=\dfrac{-171717}{232323}\)

a: -1/200<0<1/2000

b; -1789/1788<-1

-1<2009/-2010

=>-1789/1788<-2009/2010

d: -27/45=-3/5

-272727/454545=-3/5

=>-27/45=-272727/454545

a) \(\dfrac{7}{11}=1-\dfrac{4}{11}=1-\dfrac{8}{22}\)

    \(\dfrac{17}{23}=1-\dfrac{6}{23}\)

Vì \(\dfrac{8}{22}\) > \(\dfrac{6}{23}\) ⇒\(\dfrac{7}{11}>\dfrac{17}{23}\)

b) \(\dfrac{12}{48}\) = \(\dfrac{1}{4}\) = \(\dfrac{13}{52}\) < \(\dfrac{13}{27}\) 

Vì \(\dfrac{13}{52}< \dfrac{13}{27}\) ⇒ \(\dfrac{12}{48}< \dfrac{13}{27}\)  

a, -1/4<0

1/100>0

=> -1/4<1/100

b) -11/32=-11.25/ 32.25=-275/800

-25/ 76=-25.11/ 76.11=-275/ 836

=>275/800>275/836

=> -275/800< -275/836

c) -127/128> -1

-1345/1344< -1

=> 127/ -128> -1345/ 1344

d) -171717/ 232323= -17.10101/ 23.10101=-17/23

e) -1/25<0

1/1225>0

=> -1/25< 1/1225

f) 215/216<1

104/103>1

=> 215/216< 104/103

g) -12/19= 19-31/ 19= 1-31/19

-14/17= 17-31/ 17= 1-31/17

mà 31/19< 31/17

=> 1-31/19> 1-31/17

=>-12/19> -14/17

Câu 1:Ta có:\(-\frac{1}{25}< 0< \frac{1}{225}\)

Suy ra\(-\frac{1}{25}< \frac{1}{225}\)

Câu 2:

Ta có:\(\frac{-12}{19}>\frac{-14}{19}>\frac{-14}{17}\)

Suy ra\(-\frac{12}{19}>-\frac{14}{17}\)

a: -146/43<0

0<1/89

=>-146/43<1/89

b: 21/23<1

1<13/12

=>21/23<13/12

\(-\frac{13}{15}+-\frac{2}{15}=-1;-\frac{14}{16}+-\frac{2}{16}\)

Vì \(-\frac{2}{15}< -\frac{2}{16}\Rightarrow\frac{-13}{15}< -\frac{14}{16}\)

2.Gọi 3 p/số đó là x;y;z

\(-\frac{5}{8}< x< y< z< -\frac{3}{5}\)

\(-\frac{100}{160}< x< y< z< -\frac{96}{160}\)

\(\Rightarrow x=-\frac{99}{160};y=-\frac{98}{160}=-\frac{49}{80};z=-\frac{97}{160}\)
