Answer: The percentage change is 142.86%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 21 to 51? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 21\)
• \(Y = 51\)
• Percentage change calculation = \({51-21 \over 21}\) = \({30 \over 21}\) = \(1.4285714285714\)
• \(X = 21\)
• \(Y = 51\)
• Percentage change calculation = \({51-21 \over 21}\) = \({30 \over 21}\) = \(1.4285714285714\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(1.4286\) = \(142.86 \over 100 \) = \(142.86\%\)
