g) `2/(x+2) = 5/(6x)`
`=> 2. 6x = 5(x+2)`
`=> 12x = 5x + 10`
`=> 12x - 5x = 10`
`=> 7x =10`
`=> x= 10/7`
Vậy `x= 10/7`
h) `3/(5/2) = (x-1)/(2/5)`
`=> (x-1)/(2/5) = 3 : 5/2`
`=> (x-1)/(2/5) =3 . 2/5`
`=> (x-1)/(2/5) = 6/5`
`=> x-1 = 6/5 . 2/5`
`=> x-1 = 12/25`
`=> x = 12/25 + 1`
`=> x= 12/25 + 25/25`
`=> x= 37/25`
Vậy `x= 37/25`
