Answer: The percentage change is -68.72%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 991 to 310? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 991\)
• \(Y = 310\)
• Percentage change calculation = \({310-991 \over 991}\) = \({-681 \over 991}\) = \(-0.68718466195762\)
• \(X = 991\)
• \(Y = 310\)
• Percentage change calculation = \({310-991 \over 991}\) = \({-681 \over 991}\) = \(-0.68718466195762\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.6872\) = \(-68.72 \over 100 \) = \(-68.72\%\)
\(Answer: \) The percentage change is -68.72%.
\(Answer: \) The percentage change is -68.72%.
