Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 997\)
• \(Y = 1640\)
• Percentage change calculation = \({1640-997 \over 997}\) = \({643 \over 997}\) = \(0.64493480441324\)
• \(X = 997\)
• \(Y = 1640\)
• Percentage change calculation = \({1640-997 \over 997}\) = \({643 \over 997}\) = \(0.64493480441324\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
