For what you're doing, it's usually easier to use Image->Scale Image...
rather than the Scale tool. By default, if you change Width, the
Height will change automatically, keeping the aspect ratio (that's
the term for that width/height ratio) the same.

The Scale tool is for when you need to adjust the size of a layer
interactively, maybe to match something else in the image; you don't
know beforehand how big you want the layer to end up. If you prefer
using that to Image->Scale Image..., you can set it to keep the
aspect ratio the same by checking "Keep Aspect" in the tool options
dialog, or by holding the Ctrl key down as you drag.
