What is the percentage increase/decrease from 15 to 21.9?
Answer: The percentage change is 46%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 15 to 21.9? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 15\)
• \(Y = 21.9\)
• Percentage change calculation = \({21.9-15 \over 15}\) = \({6.9 \over 15}\) = \(0.46\)
• \(X = 15\)
• \(Y = 21.9\)
• Percentage change calculation = \({21.9-15 \over 15}\) = \({6.9 \over 15}\) = \(0.46\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(0.46\) = \(46 \over 100 \) = \(46\%\)
\(Answer: \) The percentage change is 46%.
