In a classroom where the expectation is built in that answers to problems in context will be written as complete sentences and numerical values from a context will always be written with the appropriate units, the task may not need to explicitly model and request it as these questions do. While students need to be able to write sentences describing ratio relationships, they also need to see and use the appropriate symbolic notation for ratios. If this is used as a teaching problem, the teacher could ask for the sentences as shown, and then segue into teaching the notation. It is a good idea to ask students to write it both ways (as shown in the solution) at some point as well.
