Answer: The percentage change is -75.32%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 85.1 to 21? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 85.1\)
• \(Y = 21\)
• Percentage change calculation = \({21-85.1 \over 85.1}\) = \({-64.1 \over 85.1}\) = \(-0.75323149236193\)
• \(X = 85.1\)
• \(Y = 21\)
• Percentage change calculation = \({21-85.1 \over 85.1}\) = \({-64.1 \over 85.1}\) = \(-0.75323149236193\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.7532\) = \(-75.32 \over 100 \) = \(-75.32\%\)
\(Answer: \) The percentage change is -75.32%.
\(Answer: \) The percentage change is -75.32%.
