Answer: The percentage change is -84.6%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 100.65 to 15.5? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 100.65\)
• \(Y = 15.5\)
• Percentage change calculation = \({15.5-100.65 \over 100.65}\) = \({-85.15 \over 100.65}\) = \(-0.84600099354198\)
• \(X = 100.65\)
• \(Y = 15.5\)
• Percentage change calculation = \({15.5-100.65 \over 100.65}\) = \({-85.15 \over 100.65}\) = \(-0.84600099354198\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.846\) = \(-84.6 \over 100 \) = \(-84.6\%\)
\(Answer: \) The percentage change is -84.6%.
\(Answer: \) The percentage change is -84.6%.
