the teacher told each student to bring in 3/8 yard of string. they all brought in a total of 13 yards. how many students will be in the class
3/8 * N=13
N= 8*13/3 students.=104/3 which is not an integer. Perhaps some student lost his head over this assignment, or some students forgot, or some dog ate one of the students string, or
your teacher messed up making this problem up.
