Answer: \(1\frac{1}{4}\) hour.

Step-by-step explanation:

Given: The number of piano solos practiced by Richard = 3

Time taken by Richard to practice each piano solo=\(\frac{5}{12}\) hour

Now, to calculate the time taken by Richard to practice all 3 piano solos, we multiply number of piano solos to the time taken to practice each piano solo, we get

The time taken by Richard to practice all 3 piano solos\(=3\times\frac{5}{12}=\frac{5}{4}=1\frac{1}{4}\) hour.

Hence, The time taken by Richard to practice all 3 piano solos=\(1\frac{1}{4}\) hour.
