    It takes 3/4 of an hour to complete a puzzle. How many puzzles can Cindy finish in 3 hours?

    We setup a proportion of time to puzzles where p is the number of puzzles Cindy can complete in 3 hours:
    3/4/1 = 3/p

    Dividing by 1 means the same as the original fraction, so we have:
    3/4 = 3/p

    Typing this proportion into the search engine, we get:
    p = 4
