Answer: The percentage change is -55.25%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 100.55 to 45? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 100.55\)
• \(Y = 45\)
• Percentage change calculation = \({45-100.55 \over 100.55}\) = \({-55.55 \over 100.55}\) = \(-0.55246146195922\)
• \(X = 100.55\)
• \(Y = 45\)
• Percentage change calculation = \({45-100.55 \over 100.55}\) = \({-55.55 \over 100.55}\) = \(-0.55246146195922\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.5525\) = \(-55.25 \over 100 \) = \(-55.25\%\)
\(Answer: \) The percentage change is -55.25%.
\(Answer: \) The percentage change is -55.25%.
