Answer: The percentage change is -76.74%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 21.5 to 5? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 21.5\)
• \(Y = 5\)
• Percentage change calculation = \({5-21.5 \over 21.5}\) = \({-16.5 \over 21.5}\) = \(-0.76744186046512\)
• \(X = 21.5\)
• \(Y = 5\)
• Percentage change calculation = \({5-21.5 \over 21.5}\) = \({-16.5 \over 21.5}\) = \(-0.76744186046512\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.7674\) = \(-76.74 \over 100 \) = \(-76.74\%\)
\(Answer: \) The percentage change is -76.74%.
\(Answer: \) The percentage change is -76.74%.
