what is the percent of increase from 5 to 7? write your answer using a percent sign (%).
Answer
Explanation:
Step1: Find the amount of increase
$7 - 5=2$
Step2: Calculate the percent - increase formula
Percent increase=$\frac{\text{amount of increase}}{\text{original amount}}\times100%$. Here, the original amount is 5 and the amount of increase is 2. So, $\frac{2}{5}\times100%$.
Step3: Simplify the expression
$\frac{2}{5}\times100% = 0.4\times100%=40%$
Answer:
$40%$
