Answer: The percentage change is -78.91%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 99.55 to 21? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 99.55\)
• \(Y = 21\)
• Percentage change calculation = \({21-99.55 \over 99.55}\) = \({-78.55 \over 99.55}\) = \(-0.78905072827725\)
• \(X = 99.55\)
• \(Y = 21\)
• Percentage change calculation = \({21-99.55 \over 99.55}\) = \({-78.55 \over 99.55}\) = \(-0.78905072827725\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.7891\) = \(-78.91 \over 100 \) = \(-78.91\%\)
\(Answer: \) The percentage change is -78.91%.
\(Answer: \) The percentage change is -78.91%.
