Answer: The percentage change is 603.3%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 91 to 640? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 91\)
• \(Y = 640\)
• Percentage change calculation = \({640-91 \over 91}\) = \({549 \over 91}\) = \(6.032967032967\)
• \(X = 91\)
• \(Y = 640\)
• Percentage change calculation = \({640-91 \over 91}\) = \({549 \over 91}\) = \(6.032967032967\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(6.033\) = \(603.3 \over 100 \) = \(603.3\%\)
