Answer: The percentage change is -75.39%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 321 to 79? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 321\)
• \(Y = 79\)
• Percentage change calculation = \({79-321 \over 321}\) = \({-242 \over 321}\) = \(-0.75389408099688\)
• \(X = 321\)
• \(Y = 79\)
• Percentage change calculation = \({79-321 \over 321}\) = \({-242 \over 321}\) = \(-0.75389408099688\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.7539\) = \(-75.39 \over 100 \) = \(-75.39\%\)
\(Answer: \) The percentage change is -75.39%.
\(Answer: \) The percentage change is -75.39%.
