Answer: The percentage change is -30.77%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 78 to 54? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 78\)
• \(Y = 54\)
• Percentage change calculation = \({54-78 \over 78}\) = \({-24 \over 78}\) = \(-0.30769230769231\)
• \(X = 78\)
• \(Y = 54\)
• Percentage change calculation = \({54-78 \over 78}\) = \({-24 \over 78}\) = \(-0.30769230769231\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.3077\) = \(-30.77 \over 100 \) = \(-30.77\%\)
