Fred is playing tennis. For every 2 of his serves that land in, 5 serves land out. If he hit 22 serves in, how many serves landed out?
If for every 2 serves that land in, 5 serves land out, the ratio of serves landing in to serves landing out is 2:5.
If Fred hit 22 serves in, then he hit (22/2) * 5 = 11 * 5 = 55 serves out.
Therefore, 55 serves landed out.
