Answer: The percentage change is -50%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 170 to 85? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 170\)
• \(Y = 85\)
• Percentage change calculation = \({85-170 \over 170}\) = \({-85 \over 170}\) = \(-0.5\)
• \(X = 170\)
• \(Y = 85\)
• Percentage change calculation = \({85-170 \over 170}\) = \({-85 \over 170}\) = \(-0.5\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.5\) = \(-50 \over 100 \) = \(-50\%\)
\(Answer: \) The percentage change is -50%.
