This Instructional Activity is a part of the Lesson 2, Unit 4, Grade 7. The purpose of this activity is to provide a context where a ratio of fractions arises naturally, and students need to find an equivalent ratio to solve the problem. Some students might try to find the biggest possible copy that will fit on the cover, which would result in a different scale factor. The digital version of the student materials includes an applet so that students can experiment with the context, because there are many related measurements within the context that can be hard to visualize.
