What is the percentage increase/decrease from 31.5 to 15?
Answer: The percentage change is -52.38%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 31.5 to 15? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 31.5\)
• \(Y = 15\)
• Percentage change calculation = \({15-31.5 \over 31.5}\) = \({-16.5 \over 31.5}\) = \(-0.52380952380952\)
• \(X = 31.5\)
• \(Y = 15\)
• Percentage change calculation = \({15-31.5 \over 31.5}\) = \({-16.5 \over 31.5}\) = \(-0.52380952380952\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.5238\) = \(-52.38 \over 100 \) = \(-52.38\%\)
\(Answer: \) The percentage change is -52.38%.
\(Answer: \) The percentage change is -52.38%.
