What is the percentage increase/decrease from 30 to 66?
Answer: The percentage change is 120%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 30 to 66? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 30\)
• \(Y = 66\)
• Percentage change calculation = \({66-30 \over 30}\) = \({36 \over 30}\) = \(1.2\)
• \(X = 30\)
• \(Y = 66\)
• Percentage change calculation = \({66-30 \over 30}\) = \({36 \over 30}\) = \(1.2\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(1.2\) = \(120 \over 100 \) = \(120\%\)
\(Answer: \) The percentage change is 120%.
\(Answer: \) The percentage change is 120%.
