This example demonstrates the conversion between fractions and decimals. Key mathematical concepts include the basic properties of fractions and the representation of decimals. Using GeoGebra commands such as Point, Sequence, and Polygon, the conversion process can be dynamically displayed. Suitable for high-grade elementary and junior high school students.

GeoGebra Commands & Parameters

  1. Point(xAxis) → A
  2. Sequence(Segment[(0 + (5 * i / j), 0), (0 + (5 * i / j), 5)], i, 0, j) → lista5
  3. Point(xAxis) → B
  4. Point(xAxis) → C
  5. Point(xAxis) → D
  6. Polygon(A, B, 4) → polígono1, a, b, c, d, E, F
  7. Polygon(C, D, 4) → polígono2, c_1, d_1, e, f, G, H
  8. Polygon(L, J, K, I) → poly1, l_1, j_2, k_1, i_1
  9. Sequence(Segment[(7 + (5 * i / j), 0), (7 + (5 * i / j), 5)], i, 0, j) → lista3
  10. Sequence(Segment[(0, (5 * g / h)), (5, (5 * g / h))], g, 0, h) → lista1
  11. Sequence(Segment[(7, (5 * g / h)), (12, (5 * g / h))], g, 0, h) → lista6
