Answer: The percentage change is -64.53%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 640 to 227? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 640\)
• \(Y = 227\)
• Percentage change calculation = \({227-640 \over 640}\) = \({-413 \over 640}\) = \(-0.6453125\)
• \(X = 640\)
• \(Y = 227\)
• Percentage change calculation = \({227-640 \over 640}\) = \({-413 \over 640}\) = \(-0.6453125\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.6453\) = \(-64.53 \over 100 \) = \(-64.53\%\)
\(Answer: \) The percentage change is -64.53%.
