Step-by-step solution

The problem

{10}\% \text{ of } {30}

  1. Change 10% to a decimal. Divide by 100.

    10\% = 10 \div 100 = 0.1
    = \textcolor{#0b5c56}{0.1} \times 30

  2. Multiply. Leave out the decimal points and multiply, then put the point back. Count the decimal places: 0.1 has 1, so the answer has 1.

    \begin{aligned} 1 \times 30 &= 30 \\[10pt] 30 \div 10 &= 3 \end{aligned}
    = \textcolor{#0b5c56}{3}

All the working together

\begin{aligned} &{10}\% \text{ of } {30} \\[8pt] &= 0.1 \times 30 && \textcolor{#5b6660}{\textsf{percent → decimal}} \\[8pt] &= \textcolor{#0b5c56}{3} && \textcolor{#5b6660}{\textsf{multiply}}\end{aligned}
