55 * 8 = 440
440 / 22 = 20 people

20 people
55 pancakes / p people = 22 pancakes / 8 people.
We then cross multiply and so multiply both sides by 8 and p. The new equation is 8 * 50 = 22 * p. 440 = 22p. So p = 440/22. Divide both sides by 22 and you get the answer, 20 people. (Also from Khan Academy)
