70/90=7/9

96/72=4/3

45/35=9/7 nha

HT

a) = 3/5 

b)2/3

c) 4/3

d) 7/5

a,3/5

b,2/3

c,4/3

d,7/5

a 3/5

b 2/3

c 4/3

d 7/5

96/72

=96:24/72:24

=3/4

`6/10=3/5`

`70/9=70/9`

`96/72=4/3`

`45/35=9/7`

`24/36=2/3`

`25/100=1/4`

$6/10=(6:2)/(10:2)=3/5$

$70/9$ ( tối giản)

$96/72=(96:24)/972:24)=4/3$

$45/35=(45:5)/(35:5)=9/7$

$24/36=(24:12)/(36:12)=2/3$

$25/100=(25:25)/(100:25)=1/4$

a. Mẫu số chung nhỏ nhất là 24

b. \(\dfrac{5}{7}\)

c. \(\dfrac{3}{4}\)

d. \(\dfrac{9}{12}\) và giữ nguyên phân số còn lại

e. \(\dfrac{3}{6};\dfrac{4}{6};\dfrac{5}{6}\)

g. \(\dfrac{9}{12};\dfrac{4}{12};\dfrac{2}{12}\)

h. \(\dfrac{15}{60};\dfrac{20}{60};\dfrac{12}{60}\)

i. \(\dfrac{10}{1}\)

a) 27 / 36 = 27 : 9 / 36 : 9 = 3/4

b) 72/96 = 72 : 24 / 96 : 24 = 3/4

c) 55 / 110 = 55 : 55 / 110 : 55 = 1/2

d) 88 / 99 = 88 : 11 / 99 : 11 = 8/9

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