Answer: The percentage change is -72.02%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 109 to 30.5? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 109\)
• \(Y = 30.5\)
• Percentage change calculation = \({30.5-109 \over 109}\) = \({-78.5 \over 109}\) = \(-0.72018348623853\)
• \(X = 109\)
• \(Y = 30.5\)
• Percentage change calculation = \({30.5-109 \over 109}\) = \({-78.5 \over 109}\) = \(-0.72018348623853\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.7202\) = \(-72.02 \over 100 \) = \(-72.02\%\)
\(Answer: \) The percentage change is -72.02%.
\(Answer: \) The percentage change is -72.02%.
