Answer: The percentage change is -22%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 10 to 7.8? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 10\)
• \(Y = 7.8\)
• Percentage change calculation = \({7.8-10 \over 10}\) = \({-2.2 \over 10}\) = \(-0.22\)
• \(X = 10\)
• \(Y = 7.8\)
• Percentage change calculation = \({7.8-10 \over 10}\) = \({-2.2 \over 10}\) = \(-0.22\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.22\) = \(-22 \over 100 \) = \(-22\%\)
\(Answer: \) The percentage change is -22%.
