What is the part to whole ratio for the six grade average of 79-70
To find the part-to-whole ratio for the six grade average of 79-70, we need to determine the average of these numbers.
The average can be found by summing up all the numbers and dividing the sum by the total number of values.
The sum of 79 and 70 is 149.
Therefore, the average is 149 divided by 2, which equals 74.5.
The part-to-whole ratio for the six grade average of 79-70 is 74.5:100.
To find the part to whole ratio for the grade average of 79-70, you first need to determine the total number of grades included in the range. In this case, the range is from 79 to 70, which is a difference of 9 grades (79 - 70 = 9). These 9 grades are the "part" of the ratio.
Next, you need to identify the denominator or "whole" of the ratio. In this case, the whole would be the total number of grades within the entire grade scale. However, you haven't specified the range of the grade scale. If you provide the full range, such as 100-0 or any other range, I can help you calculate the part to whole ratio more accurately.
To determine the part-to-whole ratio for the sixth-grade average of 79-70, we first need to understand the concept of a part-to-whole ratio.
A part-to-whole ratio is a comparison of a specific quantity (the part) to the total quantity (the whole). In this case, we need to determine the ratio of the average of the 79-70 range (the part) to the maximum possible average grade (the whole).
To find the part-to-whole ratio, we follow these steps:
Step 1: Calculate the average of the 79-70 range.
To determine the average, add up the grades (79 + 70 = 149) and divide it by the total number of grades in the range (2 in this case because there are only two grades).
Average = Sum of the grades / Total number of grades
Average = 149 / 2
Average = 74.5
Step 2: Determine the maximum possible average grade (the whole).
Since we have a range of grades from 79-70, we want to find the highest possible average within that range. In this case, it would be a range of grades from 79-79, where the average would be a perfect score of 79.
Step 3: Calculate the part-to-whole ratio.
To find the ratio, divide the average (the part) by the maximum possible average grade (the whole).
Part-to-whole ratio = Average (part) / Maximum possible average grade (whole)
Part-to-whole ratio = 74.5 / 79
Simplifying the ratio, it becomes:
Part-to-whole ratio = 0.943
Therefore, the part-to-whole ratio for the sixth-grade average of the 79-70 range is approximately 0.943.
