Answer: The percentage change is -16%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 25 to 21? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 25\)
• \(Y = 21\)
• Percentage change calculation = \({21-25 \over 25}\) = \({-4 \over 25}\) = \(-0.16\)
• \(X = 25\)
• \(Y = 21\)
• Percentage change calculation = \({21-25 \over 25}\) = \({-4 \over 25}\) = \(-0.16\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.16\) = \(-16 \over 100 \) = \(-16\%\)
\(Answer: \) The percentage change is -16%.
