Of the 112 students in the marching band, 35 were in the drum section. What is the ratio of drummers to other musicians in the band?
##5:11##
The number of other musicians in the band is:
##112 - 35 = 77##
So the ratio of drummers to other musicians can be written:
##35:77##
This can be simplified since both ##35 = 5 xx 7## and ##77 = 11 xx 7## are divisible by ##7## to:
##5:11##
