AI Drawing Prompt Reference

Create a tape diagram to represent a fraction as a product of unit fractions. Draw a long rectangular strip divided into den equal parts, with vertical subdivision lines showing each equal share. Above the strip, place several fraction “boxes” whose widths match the same unit fraction size so the upper boxes align with the corresponding segments of the main strip. Add short boundary line segments near the left and right ends of the strip to frame the tape shape. Include connecting segments that indicate the movement/alignment of the box boundaries across the strip. Finally, place the numeral “1” near the middle of the tape to serve as the key reference label, presenting the unit-fraction-product arrangement clearly.
