Understanding 109% through Shading

The video tutorial explains how to represent 109% by shading a grid. It begins by breaking down the concept of 109% as 109 per 100, equivalent to a fraction of 109/100. The tutorial then demonstrates shading a 10x10 grid to visualize 109%, starting with shading 100% of the grid and then adding an additional 9% to complete the representation of 109%. The explanation emphasizes understanding the concept rather than memorizing it.
