This example demonstrates how to arrange four given numbers—fractions, decimals, and percents—in ascending order. It explores the conversion among different representations of rational numbers, the comparison of their magnitudes, and their placement on a number line. The construction uses GeoGebra basic tools such probably points, lines, segments, vectors, and conditional statements (If) to create an interactive learning environment. It is suitable for middle and high school mathematics classrooms, focusing on number sense and ordering concepts.
