Rise over run is used to determine slope. It doesn't matter which number is bigger. It simply tells you how far up a slope climbs over what distance. So on a roof for instance, 4/12 means the roof climbs 4 inches higher every foot of width.
Either can be bigger: it is no big deal.
Yes, people trip if it is not. Remarkably almost all cultures use the same ratio.
The run is always longer, if not, I bet your staircase does not meet code
rise divided by run: a fraction, rise is y and run is x (you run on a horizontal plane) (you rise on a vertical plane)
Your run should always be longer than the rise. Current International Residential Code states the rise cannot be greater than 7-3/4" and the run cannot be less than 10". A common stair stringer has a 7" rise with a 11" run. rip your stair tread to 12" , this will over hang the run on the stringer by 1", when you install your toe kicks, use 3/4" material and you will wind up with a 1/4" overhang on each tread. Of course there are different ways to do this, but I believe this is most common.
Rise over run ! Rise _____ run
If you're talking about slope, it is rise over run. But why is it not the other way run over rise?
No, elephants are much, much bigger. A single enraged elephant can squash an adult lion like they are breaking watermelons; without barely lifting a toe. If an elephant is around, lions always run the other way!
Yes, rise divided by run
No, they run from them because their enemies are bigger and stronger than they are.
Rise/run is the slope of a line.
