How do you determine slope percentage?

• A. Horizontal plus vertical
• B. Vertical divided by Horizontal
• C. Divide the area
• D. Measure the width

Answer: (B)

The main idea is that slope percentage is the rise over the run expressed as a percent. To determine it, you take the vertical change (how much higher one point is) and divide it by the horizontal distance over which that change occurs. Then multiply by 100 to convert that ratio into a percentage. So using vertical change divided by horizontal distance is the core calculation. For example, a rise of 2 ft over 50 ft of run gives (2/50) × 100 = 4% slope. The other options don’t capture the needed rise-to-run relationship: adding dimensions, dividing area, or just measuring width don’t reflect how steep the grade is.
