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##
