    a – 3
    b – 4

    3 x ? = 12
    ? = 4

    so

    4 x 4 = 16

    Answer:

    16 B’s

    Step-by-step explanation:

    If you know there are 3/4 A’s/B’s,

    and that there are 12 A’s,

    you can set up a proportion:

    3 12

    — = —

    4 x

    cross multiplication gets you:

    48 = 3x

    solve for x.

    x = 16
