Question

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

Answer 1

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 2

Answer:
`1(1)/(4)` hour.

Explanation:

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

Time taken by Richard to practice each piano solo=
`(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*(5)/(12)=(5)/(4)=1(1)/(4)` hour.

Hence, The time taken by Richard to practice all 3 piano solos=
`1(1)/(4)` hour.
