Use the table to answer the question.
6th-Grade Average Total of Students
100–90 32
89–80 65
79–70 27
What is the part-to-part ratio for the 6th-grade averages of 100–90 to 89–80 written using a colon?
The part-to-part ratio for the 6th-grade averages of 100–90 to 89–80 is 32:65.
To find the part-to-part ratio for the 6th-grade averages of 100–90 to 89–80, we need to compare the total number of students in each average range.
The total number of students in the 100–90 range is 32, and the total number of students in the 89–80 range is 65.
So, the part-to-part ratio is 32:65.
To find the part-to-part ratio for the 6th-grade averages of 100–90 to 89–80, we need to determine the number of students in each range and then write the ratio using a colon.
According to the table:
- The number of students in the 100–90 range is 32.
- The number of students in the 89–80 range is 65.
The part-to-part ratio is calculated by dividing the number of students in one range by the number of students in the other range.
In this case, the ratio of students in the 100–90 range to the 89–80 range is:
32:65.
So the part-to-part ratio for the 6th-grade averages of 100–90 to 89–80 written using a colon is 32:65.
