Answer: The percentage change is -64.34%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 645 to 230? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 645\)
• \(Y = 230\)
• Percentage change calculation = \({230-645 \over 645}\) = \({-415 \over 645}\) = \(-0.64341085271318\)
• \(X = 645\)
• \(Y = 230\)
• Percentage change calculation = \({230-645 \over 645}\) = \({-415 \over 645}\) = \(-0.64341085271318\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.6434\) = \(-64.34 \over 100 \) = \(-64.34\%\)
\(Answer: \) The percentage change is -64.34%.
\(Answer: \) The percentage change is -64.34%.
