This GeoGebra worksheet guides students through step‑by‑step fraction simplification. It provides editable fraction inputs, visual hints such as circle arcs (CircleArc) and speech bubbles (SpeechBubbleRight) that illustrate the reduction process, and interactive open‑ended and multiple‑choice questions. The core mathematical concepts are fraction reduction, finding the greatest common divisor, and
