Step-by-step solution

The problem

{15}\% \text{ of } {90}

  1. Change 15% to a decimal. Divide by 100.

    15\% = 15 \div 100 = 0.15
    = \textcolor{#0b5c56}{0.15} \times 90

  2. Multiply. Leave out the decimal points and multiply, then put the point back. Count the decimal places: 0.15 has 2, so the answer has 2.

    \begin{aligned} 15 \times 90 &= 1350 \\[10pt] 1350 \div 100 &= 13.5 \end{aligned}
    = \textcolor{#0b5c56}{13.5}

All the working together

\begin{aligned} &{15}\% \text{ of } {90} \\[8pt] &= 0.15 \times 90 && \textcolor{#5b6660}{\textsf{percent → decimal}} \\[8pt] &= \textcolor{#0b5c56}{13.5} && \textcolor{#5b6660}{\textsf{multiply}}\end{aligned}
