    Answer:

    18 pieces

    Step-by-step explanation:

    divide 30 by 5

    you’ll get 6

    so one-fifth is equivalent to 6 of the pieces

    multiply 6 by 2

    you’ll have 2 so two-fifths is equal to 12 pieces of rice crispy treats

    subtract 12 from 30

    30 – 12 = 18

    So she took 18 pieces to school.
