Answer: The percentage change is -80.36%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 509.05 to 100? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 509.05\)
• \(Y = 100\)
• Percentage change calculation = \({100-509.05 \over 509.05}\) = \({-409.05 \over 509.05}\) = \(-0.80355564286416\)
• \(X = 509.05\)
• \(Y = 100\)
• Percentage change calculation = \({100-509.05 \over 509.05}\) = \({-409.05 \over 509.05}\) = \(-0.80355564286416\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.8036\) = \(-80.36 \over 100 \) = \(-80.36\%\)
\(Answer: \) The percentage change is -80.36%.
\(Answer: \) The percentage change is -80.36%.
