Answer: The percentage change is -21.94%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 816 to 637? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 816\)
• \(Y = 637\)
• Percentage change calculation = \({637-816 \over 816}\) = \({-179 \over 816}\) = \(-0.21936274509804\)
• \(X = 816\)
• \(Y = 637\)
• Percentage change calculation = \({637-816 \over 816}\) = \({-179 \over 816}\) = \(-0.21936274509804\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.2194\) = \(-21.94 \over 100 \) = \(-21.94\%\)
