Answer: The percentage change is -61.31%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 30.5 to 11.8? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 30.5\)
• \(Y = 11.8\)
• Percentage change calculation = \({11.8-30.5 \over 30.5}\) = \({-18.7 \over 30.5}\) = \(-0.61311475409836\)
• \(X = 30.5\)
• \(Y = 11.8\)
• Percentage change calculation = \({11.8-30.5 \over 30.5}\) = \({-18.7 \over 30.5}\) = \(-0.61311475409836\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.6131\) = \(-61.31 \over 100 \) = \(-61.31\%\)
\(Answer: \) The percentage change is -61.31%.
\(Answer: \) The percentage change is -61.31%.
