Beyond the Answer
To find \( 30 \% \) of 500, you can convert the percentage to a decimal. Simply divide 30 by 100 to get \( 0.30 \). Then, multiply \( 0.30 \) by 500: \[ 0.30 \times 500 = 150. \] So, 150 students play an instrument! Another method is to break down the calculation into simpler steps. First, find \( 10 \% \) of 500, which is \( 50 \) (just divide by 10). Then, multiply that \( 10 \% \) figure by 3 to find \( 30 \% \): \[ 3 \times 50 = 150. \] Voila! You still end up with 150 students playing an instrument, making it a systematic way to find \( 30 \% \) without much fuss!
