Step-by-step solution

The problem

{50}\% \text{ of } {15}

  1. Change 50% to a decimal. Divide by 100.

    50\% = 50 \div 100 = 0.5
    = \textcolor{#0b5c56}{0.5} \times 15

  2. Multiply. Leave out the decimal points and multiply, then put the point back. Count the decimal places: 0.5 has 1, so the answer has 1.

    \begin{aligned} 5 \times 15 &= 75 \\[3pt] 75 \div 10 &= 7.5 \end{aligned}
    = \textcolor{#0b5c56}{7.5}

All the working together

\begin{aligned} &{50}\% \text{ of } {15} \\[3pt] &= 0.5 \times 15 && \textcolor{#5b6660}{\textsf{percent → decimal}} \\[3pt] &= \textcolor{#0b5c56}{7.5} && \textcolor{#5b6660}{\textsf{multiply}}\end{aligned}
