The yearbook club had a meeting. The meeting had 16 people, which is one-fourth of the club. How many people are in the club?

Because there are 16 people and that is only 1/4 of the total amount of people there you would have to multiply 16 times 4.  $${\mathtt{16}}{\mathtt{\,\times\,}}{\mathtt{4}} = {\mathtt{64}}$$ . This means there are 64 people in the yearbook club.
