Answer: The percentage change is -51.4%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 3990 to 1939? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 3990\)
• \(Y = 1939\)
• Percentage change calculation = \({1939-3990 \over 3990}\) = \({-2051 \over 3990}\) = \(-0.5140350877193\)
• \(X = 3990\)
• \(Y = 1939\)
• Percentage change calculation = \({1939-3990 \over 3990}\) = \({-2051 \over 3990}\) = \(-0.5140350877193\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.514\) = \(-51.4 \over 100 \) = \(-51.4\%\)
\(Answer: \) The percentage change is -51.4%.
