    Given:

    4/5 of a pie left after their family picnic.

    Each slice of pie was 1/15 of the total pie.

    To find:

    The number of remaining slices of pie.

    Solution:

    Let x be the number of remaining slices of pie.

    Part of total pie in one slice = \dfrac{1}{15}

    Remaining part of total pie in x slices = \dfrac{1}{15}x

    According to the question, 4/5 of a pie left after their family picnic.

    \dfrac{1}{15}x=\dfrac{4}{5}

    Using cross multiplication, we get

    5\times x=15\times 4

    5x=60

    Divide both sides by 5.

    x=12

    Therefore, the remaining number of slices of pie is 12.
