Answer: The percentage change is -21.88%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 128 to 100? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 128\)
• \(Y = 100\)
• Percentage change calculation = \({100-128 \over 128}\) = \({-28 \over 128}\) = \(-0.21875\)
• \(X = 128\)
• \(Y = 100\)
• Percentage change calculation = \({100-128 \over 128}\) = \({-28 \over 128}\) = \(-0.21875\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.2188\) = \(-21.88 \over 100 \) = \(-21.88\%\)
\(Answer: \) The percentage change is -21.88%.
\(Answer: \) The percentage change is -21.88%.
