    Answer:64 hats

    Step-by-step explanation:

    Ratio of Blue hats = 7

    Ratio of Green hats = 4

    Ratio of purple hats = 12

    Total ratio = 7+4+12 = 23

    Total hats = 92 hats

    To get number of hats. that are not blue, we add the ratio of green and purple together = 4+12 = 16

    Number of hats that are not blue will be:

    16/23 * 92

    = 16 * 4

    = 64

    64 hats are not blue.
