This is a practice worksheet for grades 6-8 on setting up ratios and calculating the unit rate. There is also an emphasis on labeling solutions. It includes 15 questions on two pages and the answer key is an additional two pages, so the product has a total of four pages. It's easy to use for substitute teachers, also, because there is an example of each type of problem done for the students. Please contact me if find errors, so I can correct them. Thank you very much for your support!
