Question

Tìm x

\(\dfrac{25-x}{56}\) = \(\dfrac{6}{16}\)

Answer 1

`(25-x)/56 = 6/16`

`=> (25-x)xx16= 56xx6`

`=> (25-x)xx16= 336`

`=> 25-x=336:16`

`=> 25-x=21`

`=>x=25-21`

`=>x=4`

Answer 2

`(25 - x)/56 = 6/16`

`=> (25 - x)/56 = 3/8`

`=> (25 - x)/56 = 21/56`

`=> 25  -x = 21`

`=> x = 25 - 21`

`=> x = 4`

Vậy `x = 4`
