Answer: The percentage change is -51.47%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 136 to 66? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 136\)
• \(Y = 66\)
• Percentage change calculation = \({66-136 \over 136}\) = \({-70 \over 136}\) = \(-0.51470588235294\)
• \(X = 136\)
• \(Y = 66\)
• Percentage change calculation = \({66-136 \over 136}\) = \({-70 \over 136}\) = \(-0.51470588235294\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.5147\) = \(-51.47 \over 100 \) = \(-51.47\%\)
\(Answer: \) The percentage change is -51.47%.
\(Answer: \) The percentage change is -51.47%.
