What is the formula to calculate the percentage of slope?

• A. (Rise + run) ÷ 100
• B. (Run ÷ rise) × 100
• C. (Rise ÷ run) × 100
• D. (Rise - run) × 100

Answer: (C)

The formula to calculate the percentage of slope is given by (Rise ÷ Run) × 100. This formula expresses the slope as a percentage, which is a standard way to quantify the steepness of a slope. In this context, 'rise' refers to the vertical change, while 'run' refers to the horizontal distance over which that change occurs. By dividing the rise by the run, you obtain a ratio that represents how much the slope rises vertically for a specific horizontal distance. Multiplying this ratio by 100 converts it into a percentage, making it easy to understand the inclination of the slope in a more relatable format. Using this formula is crucial in various applications, especially in construction and landscaping, where understanding the slope's steepness can impact design and safety considerations. Other choices reflect misunderstandings of how slope is calculated. For instance, adding rise and run or subtracting them does not yield any meaningful representation of slope, and dividing the run by the rise provides an inverse ratio which does not correspond to the percentage slope.
