The part-to-part ratio for the 6th-grade averages of 100-90 to 89-80 written using a colon 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 write it as a ratio using a colon.
The total number of students in the 100–90 range is 32.
The total number of students in the 89–80 range is 65.
Therefore, 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, we need to compare the number of students in the 100-90 range to the number of students in the 89-80 range.
The number of students in the 100-90 range is 32, and the number of students in the 89-80 range is 65.
To write the ratio using a colon, we will place the number of students in the 100-90 range first, followed by a colon, and then the number of students in the 89-80 range.
So, the part-to-part ratio for the 6th-grade averages of 100-90 to 89-80 written using a colon is 32:65.
