Do u have a pic of the problem?
I would make both denominators the same, and the lowest one that works is 18. So I'd make 1/9 into 2/18, and 1/6 into 3/18. They already used these times so combine them to make 5/18 then subtract that from the total time they had (18/18) and you would get 13/18 they spent playing music.
X shortest piece
X+6 middle piece
X+8 longest piece
Add them
3x+14=56
3x=42
X=42/3=14

Answer:
MN-27
Step-by-step explanation:
the formula will be
NL×ML=KL^2
so substitute to get
24x=432
x=18
MN- 2x-9=2×18-9=27
