Answer: The percentage change is -91.2%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 20.45 to 1.8? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 20.45\)
• \(Y = 1.8\)
• Percentage change calculation = \({1.8-20.45 \over 20.45}\) = \({-18.65 \over 20.45}\) = \(-0.9119804400978\)
• \(X = 20.45\)
• \(Y = 1.8\)
• Percentage change calculation = \({1.8-20.45 \over 20.45}\) = \({-18.65 \over 20.45}\) = \(-0.9119804400978\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.912\) = \(-91.2 \over 100 \) = \(-91.2\%\)
\(Answer: \) The percentage change is -91.2%.
\(Answer: \) The percentage change is -91.2%.
