Step-by-step solution

The problem

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

  1. Change 40% to a decimal. Divide by 100.

    40\% = 40 \div 100 = 0.4
    = \textcolor{#0b5c56}{0.4} \times 40

  2. Multiply. Leave out the decimal points and multiply, then put the point back. Count the decimal places: 0.4 has 1, so the answer has 1.

    \begin{aligned} 4 \times 40 &= 160 \\[10pt] 160 \div 10 &= 16 \end{aligned}
    = \textcolor{#0b5c56}{16}

All the working together

\begin{aligned} &{40}\% \text{ of } {40} \\[8pt] &= 0.4 \times 40 && \textcolor{#5b6660}{\textsf{percent → decimal}} \\[8pt] &= \textcolor{#0b5c56}{16} && \textcolor{#5b6660}{\textsf{multiply}}\end{aligned}
