Step-by-step solution

The problem

{45}\% \text{ of } {300}

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

    45\% = 45 \div 100 = 0.45
    = \textcolor{#0b5c56}{0.45} \times 300

  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 300 &= 13{,}500 \\[3pt] 13{,}500 \div 100 &= 135 \end{aligned}
    = \textcolor{#0b5c56}{135}

All the working together

\begin{aligned} &{45}\% \text{ of } {300} \\[3pt] &= 0.45 \times 300 && \textcolor{#5b6660}{\textsf{percent → decimal}} \\[3pt] &= \textcolor{#0b5c56}{135} && \textcolor{#5b6660}{\textsf{multiply}}\end{aligned}
