Answer 1

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

From the table, the number of students in each range is:

• 100–90: 32 students
• 89–80: 65 students
• 79–70: 27 students

Now, we calculate the total number of students:

\[ Total\ students = 32 + 65 + 27 = 124 \]

Next, we find the part (the number of students with an average of 79–70) and the whole (the total number of students).

The part is 27 (students with an average of 79–70) and the whole is 124 (total students).

Thus, the part-to-whole ratio is:

\[ 27:124 \]

The answer is:

$$ 27:124 $$
