Answer: The percentage change is -6.72%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 685 to 639? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 685\)
• \(Y = 639\)
• Percentage change calculation = \({639-685 \over 685}\) = \({-46 \over 685}\) = \(-0.067153284671533\)
• \(X = 685\)
• \(Y = 639\)
• Percentage change calculation = \({639-685 \over 685}\) = \({-46 \over 685}\) = \(-0.067153284671533\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
