Answer: The percentage change is -42.56%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 90 to 51.7? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 90\)
• \(Y = 51.7\)
• Percentage change calculation = \({51.7-90 \over 90}\) = \({-38.3 \over 90}\) = \(-0.42555555555556\)
• \(X = 90\)
• \(Y = 51.7\)
• Percentage change calculation = \({51.7-90 \over 90}\) = \({-38.3 \over 90}\) = \(-0.42555555555556\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.4256\) = \(-42.56 \over 100 \) = \(-42.56\%\)
\(Answer: \) The percentage change is -42.56%.
\(Answer: \) The percentage change is -42.56%.
