Answer: The percentage change is 378.47%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 20.9 to 100? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 20.9\)
• \(Y = 100\)
• Percentage change calculation = \({100-20.9 \over 20.9}\) = \({79.1 \over 20.9}\) = \(3.7846889952153\)
• \(X = 20.9\)
• \(Y = 100\)
• Percentage change calculation = \({100-20.9 \over 20.9}\) = \({79.1 \over 20.9}\) = \(3.7846889952153\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(3.7847\) = \(378.47 \over 100 \) = \(378.47\%\)
\(Answer: \) The percentage change is 378.47%.
\(Answer: \) The percentage change is 378.47%.
