Answer: The percentage change is -42.03%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 138 to 80? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 138\)
• \(Y = 80\)
• Percentage change calculation = \({80-138 \over 138}\) = \({-58 \over 138}\) = \(-0.42028985507246\)
• \(X = 138\)
• \(Y = 80\)
• Percentage change calculation = \({80-138 \over 138}\) = \({-58 \over 138}\) = \(-0.42028985507246\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.4203\) = \(-42.03 \over 100 \) = \(-42.03\%\)
\(Answer: \) The percentage change is -42.03%.
\(Answer: \) The percentage change is -42.03%.
