Richard practiced each of 3 piano solos for 5/12 an hour expressed in simplest form how long did he practice in all?

In this question, the wording has to be noted very carefully. It is given that the time for practicing each of the 3 piano solos is 5/12 hour. So from this wording we understand that there are three solos and each solo takes 5/12 hours of practice by Richard. Now let us come down to the solving part.
So
For practicing 1 piano solo, Richard takes = 5/12 hours
Then
For practicing 3 piano solos the amount of time taken by Richard = (5/12) * 3
                                                                                                         = 5/4 hours
                                                                                                         = 1 1/4 hours
So the total practice time required by Richard is 1 1/4 hours.
