What is the percentage increase/decrease from 30.6 to 40?
Answer: The percentage change is 30.72%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 30.6 to 40? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 30.6\)
• \(Y = 40\)
• Percentage change calculation = \({40-30.6 \over 30.6}\) = \({9.4 \over 30.6}\) = \(0.30718954248366\)
• \(X = 30.6\)
• \(Y = 40\)
• Percentage change calculation = \({40-30.6 \over 30.6}\) = \({9.4 \over 30.6}\) = \(0.30718954248366\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(0.3072\) = \(30.72 \over 100 \) = \(30.72\%\)
\(Answer: \) The percentage change is 30.72%.
\(Answer: \) The percentage change is 30.72%.
