This example demonstrates the conversion between fractions and percentages using a clock model. Key math concepts include fractions, angles, percentage calculations, and the application of pi. It uses GeoGebra commands like Circle, Point, Segment, CircleSector, and Angle. Suitable for middle school mathematics education to visually connect fractions, percentages, and geometric shapes.

GeoGebra Commands & Parameters

  1. Circle((0, 0), 3) → c
  2. Point(Circle[O, 3]) → M
  3. Segment(O, M) → a
  4. CircleSector(O, M, A) → d
  5. Angle(M, O, A) → α
