Answer: The percentage change is -79.04%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 9109 to 1909? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 9109\)
• \(Y = 1909\)
• Percentage change calculation = \({1909-9109 \over 9109}\) = \({-7200 \over 9109}\) = \(-0.79042705017016\)
• \(X = 9109\)
• \(Y = 1909\)
• Percentage change calculation = \({1909-9109 \over 9109}\) = \({-7200 \over 9109}\) = \(-0.79042705017016\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.7904\) = \(-79.04 \over 100 \) = \(-79.04\%\)
\(Answer: \) The percentage change is -79.04%.
