Answer 1

To find the part-to-whole ratio for the 6th-grade average of 79–70, you'll need to compare the number of students in the 79–70 range to the total number of students.

From the table:

• The number of students scoring in the range 79–70 is 27.
• The total number of students is the sum of all the ranges:
  • 100–90: 32 students
  • 89–80: 65 students
  • 79–70: 27 students

Now, calculate the total number of students:

Total students = 32 + 65 + 27 = 124.

Next, form the part-to-whole ratio:

Part-to-Whole ratio = 27 (students in the range 79–70) : 124 (total students).

So, the part-to-whole ratio for the 6th-grade average of 79–70 is:

27:124.
