In collections Wiederholung: Rechnen mit Dezimalzahlen und Brüchen
This example demonstrates the subtraction of unlike fractions, particularly focusing on converting the result into an improper fraction. Core math concepts include fraction subtraction, the application of the least common multiple (LCM), and fraction conversion. The construction utilizes GeoGebra commands such as Join, LCM, RandomElement, Corner, If, Textfield, Shuffle, Append, Remove, Element, Is

GeoGebra Commands & Parameters

  1. Join(Sequence[Shuffle[Sequence[1, 36]], m, 1, 5]) → randomNosExnum
  2. LCM(numB, numD) → inputnennererweitert
  3. RandomElement({{4, 22}, {14, 17}, {15, 23}, {14, 18}, {6, 29}, {12, 24}, {4, 31}, {15, 30}, {6, 16}, {4, 22}, {6, 22}, {9, 23}, {1, 19}, {4, 22}, {2, 25}}) → startValues, {14, 17}
