If 6 adults are needed to supervise 35 students at a preschool how many are needed for 140 students?

To determine how many adults are needed for 140 students, we can set up a ratio based on the given information. If 6 adults supervise 35 students, then the number of adults required per student is 6/35. For 140 students, the calculation would be (140 students) x (6 adults/35 students) = 24 adults. Therefore, 24 adults are needed to supervise 140 students.
