Answer: The percentage change is -92.07%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 30.9 to 2.45? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 30.9\)
• \(Y = 2.45\)
• Percentage change calculation = \({2.45-30.9 \over 30.9}\) = \({-28.45 \over 30.9}\) = \(-0.92071197411003\)
• \(X = 30.9\)
• \(Y = 2.45\)
• Percentage change calculation = \({2.45-30.9 \over 30.9}\) = \({-28.45 \over 30.9}\) = \(-0.92071197411003\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.9207\) = \(-92.07 \over 100 \) = \(-92.07\%\)
\(Answer: \) The percentage change is -92.07%.
\(Answer: \) The percentage change is -92.07%.
