b) 3/4 nhân x = 7/12

giúp em gấp với ạaa 

Answer 1

a)

`x+4/5=5/6`

`=>x=5/6-4/5`

`=>x=25/30-24/30`

`=>x=1/30`

 

b)

`3/4xx x=7/12`

`=>x=7/12:3/4`

`=>x=7/12xx4/3`

`=>x=7/9`

Answer 2

`x+4/5 = 5/6`

`=>x=5/6-4/5`

`=>x= 1/30`

__

`3/4 xx x =7/12`

`=>x= 7/12 : 3/4`

`=>x= 7/12 xx4/3`

`=>x=7/9`

Answer 3

a) x là 1/30

b) x là 7/9

Answer 4

a)x=1/30

b)=7/3

nhớ tích cho mk nhé

 

Answer 5

a) x + 4/5 = 5/6

x = 5/6 - 4/5

x = 1/30 

vậy x = 1/30

b) \(\dfrac{3}{4}\) x  \(x=\dfrac{7}{12}\)

\(x=\dfrac{7}{12}:\dfrac{3}{4}\)

\(x=\dfrac{7}{9}\)

vậy x = 7/9
