This example demonstrates how to simplify fractions using GeoGebra, visually showing the reduction process. Core math concepts include GCD, properties of fractions, and rational numbers. Construction highlights use of GCD command, Segment, Line, Polygon objects, Sequence, and Random functions. Suitable for middle school students and beyond for learning fraction simplification and classroom demonstrations.

GeoGebra Commands & Parameters

  1. GCD(n_1, d_1) → h
  2. Segment(A, B) → a
  3. RandomNormal(2, 4) → c
  4. RandomBinomial(2, 3) → b
  5. nCr(4, 2) → d
  6. Sequence((x(D) + (i * a / d_1), y(D)), i, 0, d_1) → Pointbas
  7. Sequence((x(A) + (i * a / d_1), y(A)), i, 0, d_1) → Pointhaut
  8. Sequence(Segment[Element[Pointhaut, i], Element[Pointbas, i]], i, 1, d_1 + 1) → liste1
  9. Polygon(A, B, C, D) → Total, a_2, b_1, c_1, d_4
  10. Polygon(A, D, Element[Pointbas, n_1 + 1], Element[Pointhaut, n_1 + 1]) → Morceau, a_1, d_3, i, j
  11. Polygon(E, F, H, G) → poly1, e, f_1, h_1, g_1
  12. Sequence((x(G) + (i * e / (d_1 / h)), y(G)), i, 0, d_1 / h) → L2
  13. Sequence((x(E) + (i * e / (d_1 / h)), y(E)), i, 0, d_1 / h) → L3
  14. Sequence(Segment[Element[L3, i], Element[L2, i]], i, 1, d_1 / h + 1) → liste2
  15. Polygon(E, G, Element[L2, n_1 / h + 1], Element[L3, n_1 / h + 1]) → poly2, e_1, g, f, k
  16. Line(A, yAxis) → l
  17. If(h ≟ 1, 0, 5) → AnimateSpeed
