Step-by-step solution

The problem

{5}\% \text{ of } {40}

  1. Change 5% to a decimal. Divide by 100.

    5\% = 5 \div 100 = 0.05
    = \textcolor{#0b5c56}{0.05} \times 40

  2. Multiply. Leave out the decimal points and multiply, then put the point back. Count the decimal places: 0.05 has 2, so the answer has 2.

    \begin{aligned} 5 \times 40 &= 200 \\[10pt] 200 \div 100 &= 2 \end{aligned}
    = \textcolor{#0b5c56}{2}

All the working together

\begin{aligned} &{5}\% \text{ of } {40} \\[8pt] &= 0.05 \times 40 && \textcolor{#5b6660}{\textsf{percent → decimal}} \\[8pt] &= \textcolor{#0b5c56}{2} && \textcolor{#5b6660}{\textsf{multiply}}\end{aligned}
