Question

adult for every 6 children. One class has 24 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?

Answer 1

Answer:

10 adults

Step-by-step explanation:

1 adult per 6 children

there already 1 adult per class so 6 children from each class are covered

24 - 6 = 18

26 - 6 =20

28 - 6 = 22

18 + 20 + 22 =  60

60 ÷ 6 = 10

so 10 more adults are needed
