Answer: The percentage change is 144.44%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 405 to 990? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 405\)
• \(Y = 990\)
• Percentage change calculation = \({990-405 \over 405}\) = \({585 \over 405}\) = \(1.4444444444444\)
• \(X = 405\)
• \(Y = 990\)
• Percentage change calculation = \({990-405 \over 405}\) = \({585 \over 405}\) = \(1.4444444444444\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(1.4444\) = \(144.44 \over 100 \) = \(144.44\%\)
\(Answer: \) The percentage change is 144.44%.
