Answer: The percentage change is -75.83%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 90 to 21.75? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 90\)
• \(Y = 21.75\)
• Percentage change calculation = \({21.75-90 \over 90}\) = \({-68.25 \over 90}\) = \(-0.75833333333333\)
• \(X = 90\)
• \(Y = 21.75\)
• Percentage change calculation = \({21.75-90 \over 90}\) = \({-68.25 \over 90}\) = \(-0.75833333333333\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.7583\) = \(-75.83 \over 100 \) = \(-75.83\%\)
\(Answer: \) The percentage change is -75.83%.
\(Answer: \) The percentage change is -75.83%.
