A percentage is a measure of a portion of a whole, expressed as a decimal between 0 and 100. For example, if a caselet contains 20 out of 50 total elements, it has a 40% occurrence.
Similarly, a ratio is a comparison of two quantities expressed as a ratio. For instance, if two caselets have a combined frequency of 10 and 15, their ratio would be 10:15, indicating a 2:3 split.
Converting between percentages and ratios requires careful consideration and appropriate calculations. While the conversion formulas might seem complex, they involve straightforward ratios and percentages.
The key rule is to adjust the denominator (the total number of elements) accordingly. For instance, when comparing two caselets with different numbers of elements, you need to adjust the percentages accordingly.
Example:
If Caselet A has 10 elements and Caselet B has 15 elements, their combined frequency is 25.
Their ratio would be 10:15, indicating that Caselet A contributes 40% and Caselet B contributes 60%.
Converting this ratio to a percentage would be (10/25) * 100 = 40%.
Practice:
Convert the following ratios to percentages: 5:3, 7:12, and 2:5.
Calculate the percentages of each element in a caselet with 40, 60, and 80 elements, respectively
