`MSC:12`

`1/3 = (1xx4)/(3xx4)= 4/12`

`3/2=(3xx6)/(2xx6)=18/12`

`5/6=(5xx2)/(6xx2)=10/12`

`3/4=(3xx3)/(4xx3)=9/12`

`-> 4/12; 9/12; 10/12;18/12`

`->1/3; 3/4;5/6;3/2`

có `1/3=4/12`

`3/2=18/12`

`5/6=10/12`

`3/4=9/12`

vì `4<9<10<18`

`=>4/12<9/12<10/12<18/12`

`=>1/3<3/4<5/6<3/2`

`=>` sắp xếp: `1/3;3/4;5/6;3/2`

a) 4 phan 5 , 3 phan 4 , 3 phan 5 

b)5 phan 4 , 4 phan 3 , 5 phan 3 

phuong linh làm đúng rồi nhé !

Mik sẽ viết lại lời giải của bạn phuong linh

a) \(\frac{4}{5}\);   \(\frac{3}{4}\) ; \(\frac{3}{5}\)

b) \(\frac{5}{4}\) ;  \(\frac{4}{3}\) ;  \(\frac{5}{3}\)

\(\dfrac{1}{2}< \dfrac{1+1}{2+1}=\dfrac{2}{3}\)

\(\dfrac{2}{3}< \dfrac{2+1}{3+1}=\dfrac{3}{4}\)

\(\dfrac{3}{4}< \dfrac{3+1}{4+1}=\dfrac{4}{5}\)

\(\dfrac{4}{5}< \dfrac{4+1}{5+1}=\dfrac{5}{6}\)

\(\dfrac{5}{6}< \dfrac{5+1}{6+1}=\dfrac{6}{7}\)

\(\)Vậy \(\dfrac{1}{2}< \dfrac{2}{3}< \dfrac{3}{4}< \dfrac{4}{5}< \dfrac{5}{6}< \dfrac{6}{7}\)

71,62,56,44,25,7,3,1

Giúp mik với, mik đang cần gấp 

a) A

b) C

a)  =>  9, 7, 5, 2

b)   =>1, 4, 6, 8

a, 9; 7; 5; 2

b, 1; 6; 4; 8

4/5;6/6;3/2 nha!

4/5;6/6;3/2

Vi 6/6=1

   4/5<1

   3/2>1

1/3<4/5<7/3<5/2

6/8<6/7<3/2<5/2

\(\frac{3}{4}< \frac{3}{2}< \frac{5}{3}< \frac{5}{2}< \frac{6}{1}< \frac{29}{4}\)

thanks
