Answer: The percentage change is 66.67%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 390 to 650? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 390\)
• \(Y = 650\)
• Percentage change calculation = \({650-390 \over 390}\) = \({260 \over 390}\) = \(0.66666666666667\)
• \(X = 390\)
• \(Y = 650\)
• Percentage change calculation = \({650-390 \over 390}\) = \({260 \over 390}\) = \(0.66666666666667\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(0.6667\) = \(66.67 \over 100 \) = \(66.67\%\)
\(Answer: \) The percentage change is 66.67%.
\(Answer: \) The percentage change is 66.67%.
