Let's see how we can calculate this percentage: what is the percentage increase/decrease from 1977 to 7700? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 1977\)
• \(Y = 7700\)
• Percentage change calculation = \({7700-1977 \over 1977}\) = \({5723 \over 1977}\) = \(2.8947900859889\)
• \(X = 1977\)
• \(Y = 7700\)
• Percentage change calculation = \({7700-1977 \over 1977}\) = \({5723 \over 1977}\) = \(2.8947900859889\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
