Hi Rebecca, look at the following table:
Carter School Reagan School
Instrument Fraction # of students Instrument Fraction # of students
Percussion 1/3 10 Percussion 1/6 3
Brass 2/5 12 Brass 1/2 9
Woodwind 4/15 8 Woodwind 1/3 6
------------------------------------------------------------------------------------------------------------------------
Total # students 30 Total # students 18
Combined band = 30 + 18 = 48
Combined Brass = 12 + 9 = 21
Fraction of brass in combined band = 21 / 48 or 7 / 16
