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

If 6 adults are needed for 35 students, that's a ratio of 6 adults / 35 students.

To find out how many adults are needed for 140 students, we can set up a proportion:

6 adults / 35 students = x adults / 140 students

To solve for x, we can cross-multiply:

35x = 6 * 140

35x = 840

x = 840 / 35

x = 24

Therefore, 24 adults are needed to supervise 140 students.
