Answer: The percentage change is 100%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 421 to 842? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 421\)
• \(Y = 842\)
• Percentage change calculation = \({842-421 \over 421}\) = \({421 \over 421}\) = \(1\)
• \(X = 421\)
• \(Y = 842\)
• Percentage change calculation = \({842-421 \over 421}\) = \({421 \over 421}\) = \(1\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(1\) = \(100 \over 100 \) = \(100\%\)
