A total of 729 students participate in a school pep rally event. If every 30 minutes, 2/3 of the students leave, after 2 hours,
trapecia [35]

There will be 9 students left at the prep rally after 2 hours.

After 30 minutes

  • Total Number of students = 729
  • 2/3 of 729 = 486
  • Number of students left = 729 - 486 = 243

After 1 hour:

  • 2/3 of 243 = 162
  • Number of students left = 243 - 162 = 81

After 1 hour 30 minutes :

  • 2/3 of 81 = 54
  • Number of students left = 81 - 54 = 27

After 2 hours :

  • 2/3 of 27 = 18
  • Number of students left = 27 - 18 = 9

Therefore, the Number of students left after 2 hours will be 9.
