A buttress root is NOT called a prop root.
A buttress root is a big, thick, snake-like root that runs on the surface of the ground near the tree and helps to hold the tree firmly in place.
A prop root/stilt root is a root that grows out of a branch and grows down to the ground to enter into the earth and to help hold the plant steady.

what does the word prp mean in fractions
Well tell me first what is the distribu. prop. first and ill tell u.
The prop job has a two-hour head-start, so is (200 x 2) = 400 miles in the lead when the jet starts out.The jet catches up by (500 - 200) = 300 miles per hour.The jet overtakes the prop in (400 / 300) = 4/3 hour after starting out.By that time, the jet has covered (500 x 4/3) = 2,000/3 miles.The prop has covered (400) + (200 x 4/3) = (400 + 800/3) = 2,000/3 miles.Fortunately for the math, they are in the same place ...2,000/3 = [666 and 2/3] miles from the starting point.
That would depend on whether it's a rubber-band prop, a 2-engine glo-plug model, a 65-hp Piper J3, a Shorts 360, a Spruce Goose, a live 747, or something in between.
