This Instructional Activity is a part of the Lesson 11, Unit 3, Grade 6. Previously students were asked to find various percentages given 100% of a quantity. Here they are asked to find 100% of quantities given other percentages. The context does not explicitly state that the values being sought (the adult weights of two puppies) are the values for 100%, so students will first need to make that connection. Double number lines continue to be provided as a reasoning tool, but students may use a table of equivalent ratios or other methods. Those who use double number lines are likely to find them effective for the first question (find 100% of a quantity given 20%) but less straightforward for the second question (find 100% of a quantity given 30%).
