Question

PLEASE HELP MEEEEE ME ME MEEE​

Answer 1

`1\:\mathrm{year}` (one solution)

Explanation:

Let Ali's and Ahmet's ages be 3 and 4, respectively.

We have:

`(3+x)/(4+x)=(4)/(5)`

Solving for
`x`:

`5(3+x)=4(4+x),\\15+5x=16+4x,\\x=\boxed{1}`

*Since the question only stipulates that Ali and Ahmet have an age ratio of
`3:4`, there are multiple solutions to this question.
