Answer: The percentage change is -53.85%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 45.5 to 21? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 45.5\)
• \(Y = 21\)
• Percentage change calculation = \({21-45.5 \over 45.5}\) = \({-24.5 \over 45.5}\) = \(-0.53846153846154\)
• \(X = 45.5\)
• \(Y = 21\)
• Percentage change calculation = \({21-45.5 \over 45.5}\) = \({-24.5 \over 45.5}\) = \(-0.53846153846154\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.5385\) = \(-53.85 \over 100 \) = \(-53.85\%\)
\(Answer: \) The percentage change is -53.85%.
\(Answer: \) The percentage change is -53.85%.
