Answer: The percentage change is -67.8%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 205 to 66? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 205\)
• \(Y = 66\)
• Percentage change calculation = \({66-205 \over 205}\) = \({-139 \over 205}\) = \(-0.6780487804878\)
• \(X = 205\)
• \(Y = 66\)
• Percentage change calculation = \({66-205 \over 205}\) = \({-139 \over 205}\) = \(-0.6780487804878\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.678\) = \(-67.8 \over 100 \) = \(-67.8\%\)
\(Answer: \) The percentage change is -67.8%.
\(Answer: \) The percentage change is -67.8%.
