What is the part-to-whole ratio for the 6th-grade average of 79–70? Give your answer using a colon
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 calculate the ratio of the number of students in the 79–70 range to the total number of students in all ranges.
The number of students in the 79–70 range is 27, and 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 calculate the ratio of the number of students in that range to the total number of students.
Step 1: Calculate the number of students in the range of 79-70
The given information states that there are 27 students in the range of 79-70.
Step 2: Calculate the total number of students
The given information states that the total number of 6th-grade students is 32 + 65 + 27 = 124.
Step 3: Calculate the part-to-whole ratio
The part-to-whole ratio is calculated by dividing the number of students in the range of 79-70 by the total number of students:
27 / 124
Hence, the part-to-whole ratio for the 6th-grade average of 79–70 is 27:124.
