Question

Rút gọn các phân số sau:

a,\(\dfrac{27}{36}\)=

 

b,\(\dfrac{72}{96}\)=

 

c,\(\dfrac{55}{110}\)=

 

d,\(\dfrac{88}{99}\)=

Answer 1

`27/36=(27:9)/(36:9)=3/4`

`72/96=(72:24)/(96:24)=3/4`

`55/110=(55:11)/(110:11)=5/10=1/2`

`88/99=(88:11)/(99:11)=8/9`

Answer 2

`27/36=(27:9)/(36:9)=3/4`

`72/96=(72:24)/(96:24)=3/4`

`55/110=(55:11)/(110:11)=5/10=1/2`

`88/99=(88:11)/(99:11)=8/9`

Answer 3

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

Answer 4

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

72/96 = 72 : 24 / 96 : 24 = 5/10 = 1/2

55/110 = 55 : 11 / 110 : 11 = 5/10 = 1/2

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

 

Answer 5

\(a,\dfrac{27}{36}=\dfrac{27:9}{36:9}=\dfrac{3}{4}\\ b,\dfrac{72}{96}=\dfrac{72:24}{96:24}=\dfrac{3}{4}\\ c,\dfrac{55}{110}=\dfrac{55:55}{110:55}=\dfrac{1}{2}\\ d,\dfrac{88}{99}=\dfrac{88:11}{99:11}=\dfrac{8}{9}.\)
