Step-by-step Solution
To find \( 20\% \) of 150 using the percent proportion method, you can set up the proportion as follows:
\[
\frac{20}{100} = \frac{x}{150}
\]
Here, \( x \) represents the value we want to find (which is \( 20\% \) of 150).
Now, cross-multiply to solve for \( x \):
\[
20 \times 150 = 100 \times x
\]
This simplifies to:
\[
3000 = 100x
\]
Next, divide both sides by 100 to isolate \( x \):
\[
x = \frac{3000}{100} = 30
\]
Thus, \( 20\% \) of 150 is \( \boxed{30} \).
Quick Answer
\( 20\% \) of 150 is 30.
