Answer: The percentage change is -91.14%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 21991 to 1949? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 21991\)
• \(Y = 1949\)
• Percentage change calculation = \({1949-21991 \over 21991}\) = \({-20042 \over 21991}\) = \(-0.91137283434132\)
• \(X = 21991\)
• \(Y = 1949\)
• Percentage change calculation = \({1949-21991 \over 21991}\) = \({-20042 \over 21991}\) = \(-0.91137283434132\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.9114\) = \(-91.14 \over 100 \) = \(-91.14\%\)
\(Answer: \) The percentage change is -91.14%.
\(Answer: \) The percentage change is -91.14%.
