What is the part-to-whole ratio for the 6th-grade average of 79-70? Give your answer using a colon
27:65
To find the part-to-whole ratio for the 6th-grade average of 79-70, we need to determine the ratio between the number of students in the 79-70 range (the part) and the total number of students (the whole).
From the table, it is given that there are 65 students in the range of 79-70. The total number of students in the 6th-grade average is 27 + 65 = 92.
Therefore, the part-to-whole ratio for the 6th-grade average of 79-70 is 65:92.
To determine the part-to-whole ratio for the 6th-grade average of 79-70, we need to find the ratio of the number of students falling within that range (the part) to the total number of students (the whole).
From the table, we can see that under the 6th-grade average of 79-70, there are a total of 65 students. Therefore, the part is 65.
To find the whole, we need to add up the number of students in all the ranges. From the table, we can see that there are 32 students in the 100-90 range, 27 students in the 89-80 range, and 65 students in the 79-70 range. Adding these numbers together, we get:
32 + 27 + 65 = 124
So, the whole is 124.
Now, we can calculate the part-to-whole ratio by dividing the part by the whole:
65 / 124 = 0.524
The answer to the part-to-whole ratio for the 6th-grade average of 79-70 is 0.524, which can be written as 0.524:1 or simplified to 131:250.
