Shade n/m, 2n/2m, 3n/3m and so on of shapes with increasing number of parts.

This problem relates fractions with the same value but different denominators to each other. It shows the process of stepwise expansion (when read from left to right) or reduction (when read from right to left) of a fraction.

A series of shapes is shown. All shapes are of the same type, but with an increasing number of subdivisions of n, 2n 3n, and so on. With each shape, a fraction is given. The fraction always indicates the same portion of the shape, with the denominator increasing as the number of subdivisions of the shape increases. So if the first fraction is m/n, the second will be 2m/2n, the third one 3m/3n, etc.

The number of problems can be selected, and the maximum number of shapes for a problem can be specified.
