Answer: The percentage change is -66.92%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 65 to 21.5? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 65\)
• \(Y = 21.5\)
• Percentage change calculation = \({21.5-65 \over 65}\) = \({-43.5 \over 65}\) = \(-0.66923076923077\)
• \(X = 65\)
• \(Y = 21.5\)
• Percentage change calculation = \({21.5-65 \over 65}\) = \({-43.5 \over 65}\) = \(-0.66923076923077\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.6692\) = \(-66.92 \over 100 \) = \(-66.92\%\)
\(Answer: \) The percentage change is -66.92%.
\(Answer: \) The percentage change is -66.92%.
