Understanding the relationships among fractions, decimals, and percentages is a critical goal of the middle years of schooling. There are many approaches that teachers might take to help students develop this understanding; some capture general principles whereas others only illustrate specific equivalences. In this study teachers were asked to suggest three ways of convincing students that three-eighths is the same as 37.5%. The data reveal a wide range of strategies and show that different approaches may exemplify different features of the fraction-percentage relationship. The explanatory power of the examples is also considered.
