Answer: The percentage change is -80.89%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 157 to 30? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 157\)
• \(Y = 30\)
• Percentage change calculation = \({30-157 \over 157}\) = \({-127 \over 157}\) = \(-0.80891719745223\)
• \(X = 157\)
• \(Y = 30\)
• Percentage change calculation = \({30-157 \over 157}\) = \({-127 \over 157}\) = \(-0.80891719745223\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.8089\) = \(-80.89 \over 100 \) = \(-80.89\%\)
\(Answer: \) The percentage change is -80.89%.
\(Answer: \) The percentage change is -80.89%.
