Question

On Friday, 1/9 of band practice was spent trying on uniforms. The band spent 1/6 of practice on marching. The remaining practice time was spent playing music. What fraction of practice time was spent playing music?

Answer 1

1/9. = 2/18
1/6= 3/18

18-5=13
So 13/18 of the practice was spend on music

Answer 2

1/9 = 6/54

1/6 = 9/54

6/54 + 9/54 = 15/54

54/54 - 15/54 = 39/54

39/54 = 13/18

13/18 of practice time was spent playing music.
