Reducing Fractions to Lowest Terms: Conditions and Min/Max Practice

This example demonstrates how to reduce given fractions to lowest terms by canceling common factors. The key math concepts include fraction simplification, the definition of a lowest-term fraction (numerator and denominator relatively prime), and GCD/min-ratio style reasoning, with conditional logic to determine what result to display. In GeoGebra, the construction uses Min and Max to select or compare the relevant values for reduction, Textfield to show the fraction components and simplified answers, and If to apply the rule that governs the correct reduced form. Segment is used to support visual representation of relationships or proportional comparisons. Multiple fraction-related objects (e.g., fr1*/fr2*/fr3* with num/den and endpoints) together with text labels (text1–text7) structure the prompts and computed outcomes. InputBox1–InputBox6 collect user inputs, while buttons (button1, button2) control the workflow; ans1/ans2/ans3 provide the final reduced numerators and denominators. Suitable for middle-school math practice on fractions and number-theory fundamentals, and for classroom interactive exercises or self-study.
