To find the total number of teachers at Oakland Middle School, we need to calculate the number of teachers needed for each grade level separately and then add them together.
First, let's find the number of teachers for the 6th grade.
There are 128 6th graders, and we know that 3 teachers are needed for every 32 students. To calculate the number of teachers needed, we need to divide the total number of 6th graders by 32 and then multiply by 3:
Number of teachers for 6th grade = (128 / 32) * 3 = 4 * 3 = 12 teachers.
Next, let's calculate the number of teachers for the 7th grade.
There are 121 7th graders, and using the same calculation, we can find the number of teachers needed:
Number of teachers for 7th grade = (121 / 32) * 3 = 3.78 * 3 ≈ 11.34. Since we can't have a fraction of a teacher, we round this to the nearest whole number: 11 teachers.
Finally, let's calculate the number of teachers for the 8th grade.
There are 135 8th graders, and applying the same calculation:
Number of teachers for 8th grade = (135 / 32) * 3 = 4.22 * 3 ≈ 12.66. Again, we round this to the nearest whole number: 13 teachers.
To find the total number of teachers, we add up the number of teachers for each grade level:
Total number of teachers = Number of teachers for 6th grade + Number of teachers for 7th grade + Number of teachers for 8th grade
= 12 + 11 + 13
= 36 teachers.
Therefore, there are a total of 36 teachers at Oakland Middle School.
