To find the part-to-whole ratio for the 6th grade average of 79-70, we need to divide the number of students in that category by the total number of students.
From the data provided:
- The number of students with an average of 79-70 is 68.
- The total number of students is the sum of all the categories: 22 + 42 + 68 = 132.
Now, we can set up the part-to-whole ratio:
Number of students for 79-70 : Total number of students = 68 : 132.
Next, we can simplify this ratio. To do that, we can divide both numbers by their greatest common divisor (GCD). The GCD of 68 and 132 is 4.
Now, divide both:
68 ÷ 4 = 17
132 ÷ 4 = 33
Thus, the simplified part-to-whole ratio is:
**17:33**.
