①本范例演示分数除法的计算过程与可视化；②涉及核心数学概念包括分数运算、除法规则、分数表示；③构造要点：使用 GeoGebra 命令 Random 生成随机数，If 条件判断，FractionText 显示分数，Numerator/Denominator 提取分子分母，以及多个对象如 b, denominator, numerator1 等；④适合初中数学教学，用于帮助学生理解和掌握分数除法运算。
GeoGebra 命令及参数
Random(2, denominator) → denominator1Random(2, denominator) → denominator2Random(2, denominator) → denominator3If(b, 1, Random[1, denominator1]) → numerator1If(b, 1, Random[1, denominator2]) → numerator2If(b, 1, Random[1, denominator]) → numerator3Random(1, 8) → number1Random(1, 3) → number3Random(1, 4) → number2FractionText(answer1fp) → answer1fptextFractionText(answer2fp) → answer2fptextFractionText(answer3fp) → answer3fptextFractionText(answer4fp) → answer4fptextNumerator(answer4) → answer4numDenominator(answer4) → answer4denFractionText(answer3) → answer3thFractionText(answer1) → answer1fFractionText(answer2) → answer2th
