The goal of this task is to show how to apply ratio reasoning to calculate a percent. The numbers chosen make the arithmetic part of the task less demanding so that students can focus on the reasoning used to manipulate ratios. In order to do this task, students must know the meaning of percent, that is they need to know that a percent is a rate out of 100. In this case, it is the number of questions Alyssa would have answered correctly on a 100 question exam, assuming she maintains the same ratio of correct answers to questions.
