If the rate is constant they will miss 20 out of 36 attempts.

Because the scored 4 out of 9 this means they missed 5 out of 9 (#9 - 4 = 5#)

We can write the ratio of misses as:

#5:9# is the same as #x:36#

We can write this as an equation and solve for #x#:

#5/9 = x/36#

#36 * 5/9 = 36 x/36#

#36/9 * 5 = x#

#4 * 5 = x#

#x = 20#
