27:124
To find the part-to-whole ratio for the 6th-grade average of 79-70, we need to divide the number of students in the 79-70 range by the total number of students in all ranges.
The number of students in the 79-70 range is 27.
The total number of students in all ranges is 32 + 65 + 27 = 124.
Therefore, the part-to-whole ratio is 27:124.
To find the part-to-whole ratio for the 6th-grade average of 79-70, we need to determine the part (number of students in the 79-70 range) in relation to the whole (total number of students).
First, let's add up the total number of students in the 79-70 range:
79-70 Range: 27 students
Next, let's determine the total number of students in all the ranges:
Total number of students: 32 + 65 + 27 = 124 students
Now, we can calculate the part-to-whole ratio by expressing the part and the whole using a colon (:) to separate them:
Part:Whole
27:124
So, the part-to-whole ratio for the 6th-grade average of 79-70 is 27:124.
