Answer: The percentage change is -73.87%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 1990 to 520? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 1990\)
• \(Y = 520\)
• Percentage change calculation = \({520-1990 \over 1990}\) = \({-1470 \over 1990}\) = \(-0.73869346733668\)
• \(X = 1990\)
• \(Y = 520\)
• Percentage change calculation = \({520-1990 \over 1990}\) = \({-1470 \over 1990}\) = \(-0.73869346733668\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.7387\) = \(-73.87 \over 100 \) = \(-73.87\%\)
\(Answer: \) The percentage change is -73.87%.
\(Answer: \) The percentage change is -73.87%.
