If the ratio of boys to girls in the class is 8 to 5 and the number of students in the class is even, what is the minimum possible number of students in Chantel’s band class?
Chantel’s school has a rotating class schedule. Each student takes 7 classes but they only have 6 of them each day. The first day they have classes 1, 2, 3, 4, 5 and 6, the second day they have classes 7, 1, 2, 3, 4 and 5, the third day they have classes 6, 7, 1, 2, 3 and 4, and so on. How many school days pass before a day’s schedule is repeated?
PLEASE HELP =]
thanks so much!
