giúp mình  nhanh với ạ

72/96 =9/12  

64/48=4/3

132/462=12/42

 a) \(\dfrac{72}{96}\)=\(\dfrac{72:24}{96:24}\)=\(\dfrac{3}{4}\)                                                       b) \(\dfrac{64}{48}\)=\(\dfrac{64:16}{48:16}\)=\(\dfrac{4}{3}\)

 c) \(\dfrac{132}{462}\)=\(\dfrac{132:66}{462:66}\)=\(\dfrac{2}{7}\)

3/5

-3/7

4/3

\(\dfrac{105}{173}=\dfrac{3}{5};-\dfrac{151515}{353535}=-\dfrac{3}{7}\)

\(\dfrac{616}{462}=\dfrac{4}{3}\)

` 132/ 165=(132:33)/(165 : 33 )= 4/5`

Cam on

P/S Tối giản bạn nhé

\(\dfrac{132}{143}=\dfrac{132:11}{143:11}=\dfrac{12}{13}\)

\(\dfrac{143}{132}=\dfrac{13}{12};\dfrac{3535}{3737}=\dfrac{35}{37}\)

`143/132=(143:11)/(132:11)=13/12`

`3535/3737=(3535:101)/(3737:101)=35/37`

a. \(\dfrac{13}{12}\)

b. \(\dfrac{35}{37}\)

13/12 ; 35/37

Ủa Sao rút được

tối giản rồi sao mà rút gon

\(\frac{132}{55}\)=\(\frac{12}{5}\)

vì 132:11=12

   55:11=5

=>\(\frac{132}{55}\)=\(\frac{12}{5}\)

143/132=1,083

3535/3737=0,945

ko dư nha

\(\frac{143}{132}=\frac{13}{12}\)

\(\frac{3535}{3737}=\frac{35}{37}\)

a) 2/5

b) 5/9

c) 13/14

78/195=2\5

850/1530=5/9

429/462=13\14

78/195=2/5

850/1530=5/9

429/462=13/14
