Helen is plan a trip for three classes at her son's school. school rules say that classes on trips must have 1 adult for every 6 children. one has 26 children; and the third has 28 children. each class has 1 teacher. how many other adults are needed for the trip?

So first I saw that u need 1 adult with every 6 children so I did 6*4 and got 24. From that I got 4 adults with 2 leftover children. For the other class which has 28 children, u would still need 4 adults. Now since u said the teacher is included as an adult only 3 more are needed for the trip, and that is your answer.
