To find the whole given a part and the percent, you can use the formula:
\[
\text{Whole} = \frac{\text{Part}}{\text{Percent}}
\]
In this case, the part is 30 and the percent is 25%, which can be expressed as a decimal (0.25).
Now, substituting the values into the formula:
\[
\text{Whole} = \frac{30}{0.25}
\]
Calculating this:
\[
\text{Whole} = 30 \div 0.25 = 30 \times 4 = 120
\]
Therefore, 30 is 25% of **120**.
