The use of ratio and proportion, dimensional analysis, and equations to solve pharmacy calculations problems.

Introduction: To evaluate the effects of using different problem-solving approaches on the success rates of student pharmacists in solving problems throughout a pharmacy calculations course.

Methods: A survey was administered to first-year students (N = 96, response rate 100%) near the completion of a pharmacy calculations course. The survey assessed whether students used the approaches of ratio and proportion (RP) or equations vs.
