This example demonstrates the graphical representation and comparison of fractions on a number line. Key math concepts include fractions, number line, and comparison. It is constructed using GeoGebra commands like Point, Segment, and Sequence, with objects such as Nr (numerator), Dr (denominator), A (point), Zoom, a (parameter), C (point), b (point), list1 (list), B (point), D_1 (point), c (point), list2 (list), list4 (list), list3 (list), list6 (list), list5 (list), text1 (text), colour (color), list7 (list), text2 (text), d (point), text3 (text). Suitable for middle school mathematics education to visually understand the position and relationship of fractions.

GeoGebra Commands & Parameters

  1. Point(xAxis) → A
  2. Point(Circle[A, abs(Zoom)]) → C
  3. Segment(A, C) → b
  4. Sequence(((b / Nr * k), 0), k, 0, Nr) → list1
  5. Point(yAxis) → B
  6. Point(Circle[B, abs(Zoom)]) → D_1
  7. Segment(B, D_1) → c
  8. Sequence(((c / Nr * k), -1), k, 0, Nr) → list2
  9. Sequence(((c / ((Nr * Dr)) * k), -1), k, 0, (Nr * Dr)) → list4
  10. Sequence(((b / ((Nr * Dr)) * k), 0), k, 0, (Nr * Dr)) → list3
  11. Sequence(Segment[Element[list3, k], Element[list4, k]], k, 0, (Nr * Dr)) → list6
  12. Sequence(Segment[Element[list1, k], Element[list2, k]], k, 1, (Nr * Dr)) → list5
  13. Sequence(Text[k, ((b / Nr * k), (-1.5))], k, 1, Nr, 1) → list7
