(1 point)
27:124
To find the part-to-whole ratio for the 6th-grade average of 79-70, we need to determine the number of students within this range and compare it to the total number of students. Looking at the table, we can see that 27 students fall within the range of 79-70. The total number of students is given as 124 (32+65+27).
So, the part-to-whole ratio for the 6th-grade average of 79-70 is:
27:124
To find the part-to-whole ratio for the 6th-grade average of 79–70, we need to determine the number of students in that range and divide it by the total number of students.
From the table, we can see that there are 27 students in the 79–70 range. To find the total number of students, we add up the total students in all ranges: 32 + 65 + 27 = 124.
Now, we can express the part-to-whole ratio using a colon by dividing the number of students in the 79–70 range by the total number of students:
27/124
Therefore, the part-to-whole ratio for the 6th-grade average of 79–70 is 27:124.
