Answer: The percentage change is -90.7%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 215 to 20? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 215\)
• \(Y = 20\)
• Percentage change calculation = \({20-215 \over 215}\) = \({-195 \over 215}\) = \(-0.90697674418605\)
• \(X = 215\)
• \(Y = 20\)
• Percentage change calculation = \({20-215 \over 215}\) = \({-195 \over 215}\) = \(-0.90697674418605\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.907\) = \(-90.7 \over 100 \) = \(-90.7\%\)
\(Answer: \) The percentage change is -90.7%.
\(Answer: \) The percentage change is -90.7%.
