Answer: The percentage change is -87.75%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 645 to 79? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 645\)
• \(Y = 79\)
• Percentage change calculation = \({79-645 \over 645}\) = \({-566 \over 645}\) = \(-0.87751937984496\)
• \(X = 645\)
• \(Y = 79\)
• Percentage change calculation = \({79-645 \over 645}\) = \({-566 \over 645}\) = \(-0.87751937984496\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.8775\) = \(-87.75 \over 100 \) = \(-87.75\%\)
\(Answer: \) The percentage change is -87.75%.
\(Answer: \) The percentage change is -87.75%.
