Step-by-step solution

The problem

{80}\% \text{ of } {30}

  1. Change 80% to a decimal. Divide by 100.

    80\% = 80 \div 100 = 0.8
    = \textcolor{#0b5c56}{0.8} \times 30

  2. Multiply. Leave out the decimal points and multiply, then put the point back. Count the decimal places: 0.8 has 1, so the answer has 1.

    \begin{aligned} 8 \times 30 &= 240 \\[10pt] 240 \div 10 &= 24 \end{aligned}
    = \textcolor{#0b5c56}{24}

All the working together

\begin{aligned} &{80}\% \text{ of } {30} \\[8pt] &= 0.8 \times 30 && \textcolor{#5b6660}{\textsf{percent → decimal}} \\[8pt] &= \textcolor{#0b5c56}{24} && \textcolor{#5b6660}{\textsf{multiply}}\end{aligned}
