Geometers Sketchpad modeling of division by fractions

I have some ideas on this topic, but want to have input from those who have already tried and found success.
I want to model division by fractions in a constructivist way. For example. 1 divided by 1/3 = 3. Or 1/2 divided by 1/4 = 2.
I am wondering if it is better to use 2 dimensional figures like squares/rectangles. Or if it is better to use segment lengths (one dimensional).
Is it better to use the built-in calculator when starting to show the results of this algebra concept or is it better to not rely on that feature.
Any insights you can give would be helpful.
