A different eight grader has been asked to work at the face painting booth every half hour. Use division to find how many eighth-graders are needed to work at the face painting booth during the fair. Show your work.
I don't understand the division part, the way I did it was 1:00pm to 6:00pm
would be 1:00-1:30 1 student
1:30-2:00 is 1 student
2:00 2:30 is 1
3:00 to 3:30 1 student
3:30 to 4:00 1 student
4:00 to 4:30 1 student
4:30 to 5:00 1 student
5:00 to 5:30 1 student
5:30 to 6:00 1 student
answer: It will take 10 students to cover the 6 hours, but I don't understand how I'm suppose to use division can you please help. I'm studying for my PSSA'S Thank you

  1. total time from 1:00 to 6:00 is 5 hours or 300 minutes
    each half hour is 30 minutes, so
    number of students needed = 300/30 = 10
