This Problem Set is a part of the Lesson 3, Unit 1, Grade 6. Students develop an intuitive understanding of equivalent ratios by using tape diagrams to explore possible quantities of each part when given the part-to-part ratio. Students use tape diagrams to solve problems when the part-to-part ratio is given and the value of one of the quantities is given. This exercise continues to reinforce students' ability to relate ratios to the real world, as practiced in Lessons 1 and 2.
