Answer: The percentage change is -51.4%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 1640 to 797? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 1640\)
• \(Y = 797\)
• Percentage change calculation = \({797-1640 \over 1640}\) = \({-843 \over 1640}\) = \(-0.5140243902439\)
• \(X = 1640\)
• \(Y = 797\)
• Percentage change calculation = \({797-1640 \over 1640}\) = \({-843 \over 1640}\) = \(-0.5140243902439\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.514\) = \(-51.4 \over 100 \) = \(-51.4\%\)
