Explanation:

Step1: Calculate 30% of 24

To find the number of hours slept, we need to calculate \(30\%\) of \(24\). The formula for finding a percentage \(p\%\) of a number \(n\) is \(n\times\frac{p}{100}\). Here, \(n = 24\) and \(p=30\).
So, the calculation is \(24\times\frac{30}{100}\).

Step2: Simplify the expression

First, simplify \(\frac{30}{100}=\frac{3}{10}\). Then, \(24\times\frac{3}{10}=\frac{24\times3}{10}=\frac{72}{10} = 7.2\)

Answer:

\(7.2\)
