Represent Draw a rectangle. Shade seven eighths of it. What percent of the rectangle is not shaded?

If you shade seven-eighths of the rectangle, that leaves one-eighth unshaded. To calculate the percentage of the rectangle that is not shaded, you can convert one-eighth into a percentage. Since there are 100 percent in total, one-eighth is equal to 12.5 percent. Therefore, 12.5 percent of the rectangle remains unshaded! Fun fact: Rectangles have been utilized since ancient times, with early mathematics in civilizations like the Egyptians and Babylonians documenting their properties. They were used for practical applications such as land measurement and construction, which shows how geometric shapes have been vital throughout history! In real-world applications, understanding fractions and percentages is crucial, especially in fields like cooking or budget management. For example, if you’re baking and the recipe calls for 8 cups of flour but you only need to use 1 cup, calculating how much of the total amount you're using helps in scaling recipes up or down!
