Step-by-step solution

The problem

{45}\% \text{ of } {10}

  1. Change 45% to a decimal. Divide by 100.

    45\% = 45 \div 100 = 0.45
    = \textcolor{#0b5c56}{0.45} \times 10

  2. Multiply. Leave out the decimal points and multiply, then put the point back. Count the decimal places: 0.45 has 2, so the answer has 2.

    \begin{aligned} 45 \times 10 &= 450 \\[10pt] 450 \div 100 &= 4.5 \end{aligned}
    = \textcolor{#0b5c56}{4.5}

All the working together

\begin{aligned} &{45}\% \text{ of } {10} \\[8pt] &= 0.45 \times 10 && \textcolor{#5b6660}{\textsf{percent → decimal}} \\[8pt] &= \textcolor{#0b5c56}{4.5} && \textcolor{#5b6660}{\textsf{multiply}}\end{aligned}
