Richard practiced each of 3 piano solos for 5/12 hour. Expressed in simplest form, how long did he practice in all.



Answer :

5\12 * 3 = 15/12 

15/12 = 1 3/12

1 3/12 = 1 1/4

so he practiced for 1 hour and 15 min

Answer: [tex]1\frac{1}{4}[/tex] hour.

Step-by-step explanation:

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

Time taken by Richard to practice each piano solo=[tex]\frac{5}{12}[/tex] 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[tex]=3\times\frac{5}{12}=\frac{5}{4}=1\frac{1}{4}[/tex] hour.

Hence, The time taken by Richard to practice all 3 piano solos=[tex]1\frac{1}{4}[/tex] hour.
