A plumber needs 4 sections of pipe 2and 7/8 feet long. Can this be cut from a 12 ft. section? If so, how much pipe will be left over? If not, why not?
I came up with yes, you will use 11 1/8th amount and have a section of 1 and 1/8th left. Is this correct?

not exactly. yes, the plumber will have enough, but I came up with 11 1/2 ft
2 7/8 * 4 = 23/8 * 4 = 23/2 = 11 R1 or rather 1/2 (remainder)
Hope that helped!
