what is the percent of increase from 4 to 5? write your answer using a percent sign (%).
Answer
# Explanation:
## Step1: Calculate the amount of increase
The amount of increase is \(5 - 4=1\).
## Step2: Use the percent - increase formula
The percent - increase formula is \(\text{Percent Increase}=\frac{\text{Amount of Increase}}{\text{Original Amount}}\times100\%\).
Here, the original amount is \(4\) and the amount of increase is \(1\). So \(\text{Percent Increase}=\frac{1}{4}\times 100\%\).
Since \(\frac{1}{4}=0.25\), then \(0.25\times100\% = 25\%\).
# Answer:
\(25\%\)
