    Spent half on movie tickets:

    Movie Tickets = 1/2

    Remaining = 1 - 1/2 = 1/2

    Spent half of remaining on popcorn:

    Popcorn = 1/2 of 1/2

    Popcorn = 1/2 x 1/2

    Popcorn = 1/4

    Remaining = 1/2 - 1/4 = 1/4

    Spent half on remaining on small drink:

    Drink = 1/2 of 1/4

    Drink = 1/2 x 1/4

    Drink = 1/8

    Left:

    1/4 - 1/8 = 2/8 - 1/8 = 1/8

    Ans: 1/8 of the money is left.
