Answer: The percentage change is -64.52%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 217 to 77? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 217\)
• \(Y = 77\)
• Percentage change calculation = \({77-217 \over 217}\) = \({-140 \over 217}\) = \(-0.64516129032258\)
• \(X = 217\)
• \(Y = 77\)
• Percentage change calculation = \({77-217 \over 217}\) = \({-140 \over 217}\) = \(-0.64516129032258\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.6452\) = \(-64.52 \over 100 \) = \(-64.52\%\)
\(Answer: \) The percentage change is -64.52%.
\(Answer: \) The percentage change is -64.52%.
