Answer: The percentage change is -75.71%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 420 to 102? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 420\)
• \(Y = 102\)
• Percentage change calculation = \({102-420 \over 420}\) = \({-318 \over 420}\) = \(-0.75714285714286\)
• \(X = 420\)
• \(Y = 102\)
• Percentage change calculation = \({102-420 \over 420}\) = \({-318 \over 420}\) = \(-0.75714285714286\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.7571\) = \(-75.71 \over 100 \) = \(-75.71\%\)
\(Answer: \) The percentage change is -75.71%.
\(Answer: \) The percentage change is -75.71%.
