I would love to receive a very detail information on how to calculate a 1/9 of a mile, because I know that a mile is 5280ft and a 1/2 of that mile is 2640 and 1/2 of a 1/2, which is a 1/4 would be 1320. A 1/2 of the 1/4 mile would be 660 which is an 1/8 of a mile or whole mile. If your are giving me the answer from an algerbric formula, than please explan each step to me like an elementary child that I may fully understand. Thanks!
