Answer key and explanations

  1. C. \(100\)

    \(40\%\) of \(250\) is \(0.40\times250=100\) students.

  2. A. \(60\)

    \(30\%\) of \(200\) is \(0.30\times200=60\) people.

  3. A. \(45\)

    \(25\%\) of \(180\) is \(0.25\times180=45\) customers.

  4. B. \(60\)

    \(20\%\) of \(300\) is \(0.20\times300=60\) students.

  5. D. 90°

    Each section represents \(25\%\). The central angle is \(0.25\times360°=90°\).

  6. C. \(225\)

    \(45\%\) of \(500\) is \(0.45\times500=225\) commuters.

  7. D. 72°

    \(\frac{1}{5}\) equals \(20\%\). The central angle is \(0.20\times360°=72°\).

  8. A. \(100\)

    \(50\%\) of \(200\) is \(0.50\times200=100\) customers.
