Proportional Fraction Rods

This is a version of Arrangement 4 that lets you pick different sets of rods with a "Try Again" button. Can you arrange the rods so that every rod in a column is divided into the same number of red and blue chunks? Can you also arrange them so that each rod in a row has the same chunk size? rods that can be arranged this way are proportional.

Don't forget--after you have arranged the rods once, you can use the "Try Again" button to try to arrange a different set of rods.
