AI Drawing Prompt Reference
Draw a geometric model for fraction division. Start with three circles of equal radius, each centered at a distinct point. Within each circle, divide the circumference into equal parts based on the denominator, rotating from a starting point by the same angle repeatedly to create multiple division points. Connect each adjacent point to the center to form a series of equal sector angles. The three circles represent the dividend, divisor, and result, and comparing the number and angle of sectors in each circle visually demonstrates the fraction division operation. All circles share the same radius, and the rotation angle is determined by the denominator, resulting in a symmetric and evenly distributed layout.
