What is the percentage increase/decrease from 101.7 to 30?
Answer: The percentage change is -70.5%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 101.7 to 30? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 101.7\)
• \(Y = 30\)
• Percentage change calculation = \({30-101.7 \over 101.7}\) = \({-71.7 \over 101.7}\) = \(-0.70501474926254\)
• \(X = 101.7\)
• \(Y = 30\)
• Percentage change calculation = \({30-101.7 \over 101.7}\) = \({-71.7 \over 101.7}\) = \(-0.70501474926254\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.705\) = \(-70.5 \over 100 \) = \(-70.5\%\)
\(Answer: \) The percentage change is -70.5%.
\(Answer: \) The percentage change is -70.5%.
