What is the percentage increase/decrease from 20.5 to 20?
Answer: The percentage change is -2.44%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 20.5 to 20? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 20.5\)
• \(Y = 20\)
• Percentage change calculation = \({20-20.5 \over 20.5}\) = \({-0.5 \over 20.5}\) = \(-0.024390243902439\)
• \(X = 20.5\)
• \(Y = 20\)
• Percentage change calculation = \({20-20.5 \over 20.5}\) = \({-0.5 \over 20.5}\) = \(-0.024390243902439\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.0244\) = \(-2.44 \over 100 \) = \(-2.44\%\)
\(Answer: \) The percentage change is -2.44%.
\(Answer: \) The percentage change is -2.44%.
