On friday 1/6 of band practice was spent trying on uniforms. the band spent 1/4 practice on marching. the remaining practice time was spent playing music.

7/12 of the band practice time is spent on playing music.

Step-by-step explanation:

The data we have is:

On friday, the band spent 1/6 of the time in triyinh uniforms and 1/4 of the time on practice marching.

Then the amount of time that the band did not practice music is:

1/6 + 1/4 of their total time:

we know that 12 is a common multiple of both, 6 and 4, so we can write this as:

2/12 + 3/12 = 5/12

Then the total time that the band practices music is:

1 - 5/12 = 7/12
