Answer: The percentage change is -52.89%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 45 to 21.2? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 45\)
• \(Y = 21.2\)
• Percentage change calculation = \({21.2-45 \over 45}\) = \({-23.8 \over 45}\) = \(-0.52888888888889\)
• \(X = 45\)
• \(Y = 21.2\)
• Percentage change calculation = \({21.2-45 \over 45}\) = \({-23.8 \over 45}\) = \(-0.52888888888889\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.5289\) = \(-52.89 \over 100 \) = \(-52.89\%\)
\(Answer: \) The percentage change is -52.89%.
\(Answer: \) The percentage change is -52.89%.
