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.
