The purpose of this task is for students to learn to reason about whether or not ratios are equivalent using a diagram. If students are familiar with different types of diagrams, they might be left to decide on an appropriate representation. Or a teacher might use this task to practice or promote the use of a particular type of diagram. The type of diagram shown in the solution is a parallel tape diagram, but a double number line diagram or a ratio table could also work nicely if students are familiar with them.
