I suppose they want you to setup a left and right statement and find the answer to x?

On a map you usually see f.e 1:100... and 1 inch f.x would be the representation of a value hundred times that.

It is a proportional description.

... so try solve this:

$\displaystyle \frac{s}{n} = \frac{x}{(n+1)} $
