Answer: The percentage change is -8.68%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 21.9 to 20? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 21.9\)
• \(Y = 20\)
• Percentage change calculation = \({20-21.9 \over 21.9}\) = \({-1.9 \over 21.9}\) = \(-0.08675799086758\)
• \(X = 21.9\)
• \(Y = 20\)
• Percentage change calculation = \({20-21.9 \over 21.9}\) = \({-1.9 \over 21.9}\) = \(-0.08675799086758\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.0868\) = \(-8.68 \over 100 \) = \(-8.68\%\)
\(Answer: \) The percentage change is -8.68%.
\(Answer: \) The percentage change is -8.68%.
