Answer: The percentage change is -63.96%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 55.5 to 20? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 55.5\)
• \(Y = 20\)
• Percentage change calculation = \({20-55.5 \over 55.5}\) = \({-35.5 \over 55.5}\) = \(-0.63963963963964\)
• \(X = 55.5\)
• \(Y = 20\)
• Percentage change calculation = \({20-55.5 \over 55.5}\) = \({-35.5 \over 55.5}\) = \(-0.63963963963964\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.6396\) = \(-63.96 \over 100 \) = \(-63.96\%\)
\(Answer: \) The percentage change is -63.96%.
\(Answer: \) The percentage change is -63.96%.
