What is the percentage increase/decrease from 121 to 100?
Answer: The percentage change is -17.36%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 121 to 100? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 121\)
• \(Y = 100\)
• Percentage change calculation = \({100-121 \over 121}\) = \({-21 \over 121}\) = \(-0.17355371900826\)
• \(X = 121\)
• \(Y = 100\)
• Percentage change calculation = \({100-121 \over 121}\) = \({-21 \over 121}\) = \(-0.17355371900826\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.1736\) = \(-17.36 \over 100 \) = \(-17.36\%\)
\(Answer: \) The percentage change is -17.36%.
\(Answer: \) The percentage change is -17.36%.
