Answer: The percentage change is -86.99%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 661 to 86? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 661\)
• \(Y = 86\)
• Percentage change calculation = \({86-661 \over 661}\) = \({-575 \over 661}\) = \(-0.86989409984871\)
• \(X = 661\)
• \(Y = 86\)
• Percentage change calculation = \({86-661 \over 661}\) = \({-575 \over 661}\) = \(-0.86989409984871\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
