Step-by-step solution

The problem

{25}\% \text{ of } {30}

  1. Change 25% to a decimal. Divide by 100.

    25\% = 25 \div 100 = 0.25
    = \textcolor{#0b5c56}{0.25} \times 30

  2. Multiply. Leave out the decimal points and multiply, then put the point back. Count the decimal places: 0.25 has 2, so the answer has 2.

    \begin{aligned} 25 \times 30 &= 750 \\[10pt] 750 \div 100 &= 7.5 \end{aligned}
    = \textcolor{#0b5c56}{7.5}

All the working together

\begin{aligned} &{25}\% \text{ of } {30} \\[8pt] &= 0.25 \times 30 && \textcolor{#5b6660}{\textsf{percent → decimal}} \\[8pt] &= \textcolor{#0b5c56}{7.5} && \textcolor{#5b6660}{\textsf{multiply}}\end{aligned}
