Explanation:

Step1: Find total parts of the ratio

The ratio of adults to children is \(5:3\), so total parts \(= 5 + 3 = 8\).

Step2: Find value of one part

Total people are 144, so value of one part \(= \frac{144}{8} = 18\).

Adults are 5 parts, so number of adults \(= 5\times18 = 90\).

Answer:

90
