AI Drawing Prompt Reference

Draw a geometric representation of adding two fractions. Start by creating a circle and divide it into n1 sectors, each representing a fraction. Then, create another circle of the same size and divide it into n2 sectors for the second fraction. Overlay the sectors of both circles, using different colors to distinguish them, to visualize the addition of fractions. Add text labels to display the values of n1, n2, and the fractions for clarity.
