Calculate the Percentage: Converting 30 over 100 to Percent Form

In order to determine what percentage 30 is out of 100, you can use the following formula:

$\text{Percentage} = \frac{\text{Part}}{\text{Whole}} \times 100$

We begin by substituting the given values into the formula:

$\text{Percentage} = \frac{30}{100} \times 100$

We then proceed to simplify the expression:

$\text{Percentage} = 30\%$

Therefore, 30 out of 100 is 30%.
