Use these applets to implement the approach presented in The Well-Chosen Rectangle.

Basic idea: use the denominators of the two fractions as the rectangles' dimensions.

- Use the red
**O**to adjust the rectangle dimensions. - Use the blue
**O**'s to shade fractions. - You might hide the
**O**'s before taking a screenshot.
