DescriptionIn this short clip, James explains to Robert B. Davis his solution to the problem: Which is larger, one fourth or one ninth, and by how much? After some questioning, he explains that the train (i.e., a composite rod made by laying the rods end-to-end) of three orange rods and a dark green rod was called one, and that the blue rod was one fourth and the purple rod was one ninth. He showed that the difference between the two was the length of five white rods, or five thirty-sixths.
