Answer: The percentage change is -84.9%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 510 to 77? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 510\)
• \(Y = 77\)
• Percentage change calculation = \({77-510 \over 510}\) = \({-433 \over 510}\) = \(-0.84901960784314\)
• \(X = 510\)
• \(Y = 77\)
• Percentage change calculation = \({77-510 \over 510}\) = \({-433 \over 510}\) = \(-0.84901960784314\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.849\) = \(-84.9 \over 100 \) = \(-84.9\%\)
\(Answer: \) The percentage change is -84.9%.
