This Problem Set is a part of the Lesson 5, Unit 1, Grade 6. Students use tape diagrams to find an equivalent ratio when given the part-to-part ratio and the total of those two quantities. Students use tape diagrams to find an equivalent ratio when given the part-to-part ratio and the difference between those two quantities. Students make the connection between the constant in the definition of equivalent ratios and the value of the unit in the tape diagram used to solve ratio problems.
