What is the percentage increase/decrease from 310 to 31?
Answer: The percentage change is -90%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 310 to 31? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 310\)
• \(Y = 31\)
• Percentage change calculation = \({31-310 \over 310}\) = \({-279 \over 310}\) = \(-0.9\)
• \(X = 310\)
• \(Y = 31\)
• Percentage change calculation = \({31-310 \over 310}\) = \({-279 \over 310}\) = \(-0.9\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.9\) = \(-90 \over 100 \) = \(-90\%\)
\(Answer: \) The percentage change is -90%.
