AI Drawing Prompt Reference

Create a visual for fraction subtraction. Arrange three horizontal rows of equal-width rectangles on a coordinate plane. The top row shows the minuend with some rectangles highlighted, the middle row shows the subtrahend with a different number highlighted, and the bottom row displays the difference. Use sliders to adjust the numerators and denominators. Ensure all rectangles are aligned vertically and have consistent width for easy comparison.
