If slope rises 9 inches over 45 inches run, what is the Run/Rise ratio?

Explanation:
Run/Rise ratio compares horizontal distance to vertical rise. Here the run is 45 inches and the rise is 9 inches, so you divide 45 by 9 to get 5. That means the Run/Rise ratio is 5 to 1, usually written as 5. This matches the correct choice. The other numbers would represent the inverse or different measures (for example, rise over run would be 9/45 = 0.2), which isn’t what’s asked here.
