\( \begin{array}{ll}\text { (a) } 27 \text { is what percent of } 60 ? & \square \\ \text { (b) } 75 \% \text { of } 48 \text { is what number? }\end{array} \)

1. **(a)** To find what percent \(27\) is of \(60\), we set up the equation \[ \frac{p}{100} \times 60 = 27. \] Solving for \( p \): \[ \frac{p}{100} = \frac{27}{60} \quad \Longrightarrow \quad p = \frac{27 \times 100}{60} = \frac{2700}{60} = 45. \] So, \(27\) is \(45\%\) of \(60\). 2. **(b)** To find \(75\%\) of \(48\), we calculate \[ \frac{75}{100} \times 48 = 0.75 \times 48. \] Recognizing that \(0.75 = \frac{3}{4}\), we have \[ \frac{3}{4} \times 48 = 36. \] Thus, the answers are: - (a) \(45\%\). - (b) \(36\).
