\(a,x-\dfrac{1}{4}=\dfrac{5}{3}\\ x=\dfrac{5}{3}+\dfrac{1}{4}\\ x=\dfrac{20}{12}+\dfrac{3}{12}\\ x=\dfrac{23}{12}\\ b,x:\dfrac{2}{3}=\dfrac{1}{2}\\ x=\dfrac{1}{2}\times\dfrac{2}{3}\\ x=\dfrac{1}{3}\)

Answer 2

1.17/12

2.1/3

Answer 3

`=> x= 13/12`

Vậy `x= 13/12`

`b.``x:2/3= 1/2`

`=> x= 1/2 xx 2/3`

`=> x= 1/3`

Vậy `x= 1/3`
