Answer 1

To find the part-to-whole ratio for the 6th-grade average of 79–70, we first need to identify the number of students in that average range and the total number of students.

From the table:

• The number of students with an average of 79–70 is 27.
• The total number of students is the sum of all ranges: 32 (100–90) + 65 (89–80) + 27 (79–70) = 124.

Now, we can express the part (students with an average of 79–70) to the whole (total students) as a ratio:

Part-to-whole ratio = Number of students in the range : Total number of students = 27 : 124

Thus, the part-to-whole ratio for the 6th-grade average of 79–70 is 27:124.
