Explanation:

Step1: Convert hours to minutes

Since 1 hour = 60 minutes, \(\frac{1}{2}\) of an hour is \(\frac{1}{2}\times60 = 30\) minutes, and \(\frac{1}{4}\) of an hour is \(\frac{1}{4}\times60=15\) minutes.

Step2: Sum up the time

Add the time for making, baking and decorating: \(30 + 15+45\). First, \(30+15 = 45\), then \(45 + 45=90\) minutes.

Answer:

90
