The decimal you have, 1.6875 is elevensixteenths. Similarly five and seveneights is 5 + 7/8 = 5 + 0.875 = 5.875 inches. The question you ask can be answered by asking "How many times do you need to expand 1.0625 to get to 5.875?" The answer is 5.875/1.0625 = 5.529. Thus 5 7/8 is 5.529 times as large as 1 1/16. Hence the 5 7/8 on the paper represents 5.529 time 90 feet or 497.65 feet. I hope this helps,
