What is the percentage increase/decrease from 101 to 81?
Answer: The percentage change is -19.8%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 101 to 81? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 101\)
• \(Y = 81\)
• Percentage change calculation = \({81-101 \over 101}\) = \({-20 \over 101}\) = \(-0.1980198019802\)
• \(X = 101\)
• \(Y = 81\)
• Percentage change calculation = \({81-101 \over 101}\) = \({-20 \over 101}\) = \(-0.1980198019802\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.198\) = \(-19.8 \over 100 \) = \(-19.8\%\)
\(Answer: \) The percentage change is -19.8%.
\(Answer: \) The percentage change is -19.8%.
