Step-by-step solution

The problem

{18}\% \text{ of } {40}

  1. Change 18% to a decimal. Divide by 100.

    18\% = 18 \div 100 = 0.18
    = \textcolor{#0b5c56}{0.18} \times 40

  2. Multiply. Leave out the decimal points and multiply, then put the point back. Count the decimal places: 0.18 has 2, so the answer has 2.

    \begin{aligned} 18 \times 40 &= 720 \\[10pt] 720 \div 100 &= 7.2 \end{aligned}
    = \textcolor{#0b5c56}{7.2}

All the working together

\begin{aligned} &{18}\% \text{ of } {40} \\[8pt] &= 0.18 \times 40 && \textcolor{#5b6660}{\textsf{percent → decimal}} \\[8pt] &= \textcolor{#0b5c56}{7.2} && \textcolor{#5b6660}{\textsf{multiply}}\end{aligned}
