Question

on Friday, 1/6 of band practice was spent trying on uniforms. The band spent 1/4 of practice on marching, the remaining practice time was spent playing music. what fraction of the time was spent playing music?

Answer 1

7/12 because 1/4 = 6/24 and 1/6 = 4/24 and if u add them you get 10/24 which leaves 14/24 which simplifies to 7/12

Answer 2

Answer:
`(7)/(12)`

Explanation:

Let the total time of band practice be 't'.

Then, Practice spent by band on uniforms =
`(1)/(6)t`

Practice spent by band on marching =
`(1)/(4)t`

Then the remaining time=
`t-(1)/(6)t-(1)/(4)t`

⇒ The remaining time =
`(12t-2t-3t)/(12)`

⇒ The remaining time =
`(7t)/(12)`

Thus,
`(7)/(12)` of time was spent on playing music.
