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
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
Thank you.
Of course! Division can be used to solve this problem and find the number of eighth-graders needed to work at the face painting booth during the fair. Let's break it down step by step.
To calculate the number of eighth-graders needed, we need to divide the total time (6 hours) by the duration of each shift (30 minutes or half an hour).
Since there are 60 minutes in an hour, 30 minutes is equal to half of an hour. Therefore, we can calculate:
6 hours ÷ 0.5 hours/shift = 12 shifts
Based on your explanation, there is a need for one student every half hour (or every shift). So, if there are 12 shifts in total, we multiply that by one student per shift:
12 shifts × 1 student/shift = 12 students
Therefore, according to your schedule and the requirement of one student per shift, you would need 12 students to work at the face painting booth during the fair.
Using division helps us find the solution in a more mathematical way by dividing the total time by the duration of each shift. This is especially useful when dealing with larger numbers or more complex scenarios.
