Step-by-step solution

The problem

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

  1. Change 30% to a decimal. Divide by 100.

    30\% = 30 \div 100 = 0.3
    = \textcolor{#0b5c56}{0.3} \times 80

  2. Multiply. Leave out the decimal points and multiply, then put the point back. Count the decimal places: 0.3 has 1, so the answer has 1.

    \begin{aligned} 3 \times 80 &= 240 \\[10pt] 240 \div 10 &= 24 \end{aligned}
    = \textcolor{#0b5c56}{24}

All the working together

\begin{aligned} &{30}\% \text{ of } {80} \\[8pt] &= 0.3 \times 80 && \textcolor{#5b6660}{\textsf{percent → decimal}} \\[8pt] &= \textcolor{#0b5c56}{24} && \textcolor{#5b6660}{\textsf{multiply}}\end{aligned}
