Step-by-step solution

The problem

{90}\% \text{ of } {10}

  1. Change 90% to a decimal. Divide by 100.

    90\% = 90 \div 100 = 0.9
    = \textcolor{#0b5c56}{0.9} \times 10

  2. Multiply. Leave out the decimal points and multiply, then put the point back. Count the decimal places: 0.9 has 1, so the answer has 1.

    \begin{aligned} 9 \times 10 &= 90 \\[10pt] 90 \div 10 &= 9 \end{aligned}
    = \textcolor{#0b5c56}{9}

All the working together

\begin{aligned} &{90}\% \text{ of } {10} \\[8pt] &= 0.9 \times 10 && \textcolor{#5b6660}{\textsf{percent → decimal}} \\[8pt] &= \textcolor{#0b5c56}{9} && \textcolor{#5b6660}{\textsf{multiply}}\end{aligned}
