This Instructional Activity is a part of the Lesson 9, Unit 9, Grade 7. This challenging activity examines how measurement errors behave when 3 quantities are multiplied (versus 2 quantities in the previous activity). In other words, if I have measurements a, b, and c each with a maximum error of 5%, what percent error can a × b ×c have? The arithmetic and algebraic demands of this task are high because students take a product of three quantities that each have a maximum percent error of 5%.
