Answer: The percentage change is -39.35%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 643 to 390? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 643\)
• \(Y = 390\)
• Percentage change calculation = \({390-643 \over 643}\) = \({-253 \over 643}\) = \(-0.39346811819596\)
• \(X = 643\)
• \(Y = 390\)
• Percentage change calculation = \({390-643 \over 643}\) = \({-253 \over 643}\) = \(-0.39346811819596\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.3935\) = \(-39.35 \over 100 \) = \(-39.35\%\)
\(Answer: \) The percentage change is -39.35%.
\(Answer: \) The percentage change is -39.35%.
