Answer: The percentage change is 102.02%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 9.9 to 20? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 9.9\)
• \(Y = 20\)
• Percentage change calculation = \({20-9.9 \over 9.9}\) = \({10.1 \over 9.9}\) = \(1.020202020202\)
• \(X = 9.9\)
• \(Y = 20\)
• Percentage change calculation = \({20-9.9 \over 9.9}\) = \({10.1 \over 9.9}\) = \(1.020202020202\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(1.0202\) = \(102.02 \over 100 \) = \(102.02\%\)
\(Answer: \) The percentage change is 102.02%.
\(Answer: \) The percentage change is 102.02%.
