2/5 of instruments= brass
1/3 of instruments= percussion
so add 2/5 and 1/3= 6/15+5/15= 11/15

So 15/15-11/15= 4/15
So Woodwinds make up 4/15 of the band

First calculate how much of the whole band the brass and percussion take.
2/5+1/3= 6/15+5/15= 11/15
A whole is 1, which is 15/15, so
15/15-11/15=4/15
4/15 of the band is woodwinds.
