    Given:

    ratio of stickers to erasers: 3 to 8

    She has 12 stickers.

    3:8 = 12:x

    3x = 8*12

    3x = 96

    x = 96/3

    x = 32 erasers.

    Mrs. Robbins has 32 erasers.

    Stickers : erasers = 3 : 8

    12 : e = 3:8

    12/e = 3/8

    3*e = 12*8

    e = 12*8/3

    e = 32

    Erasers = 32.
