  1. Let's first find the common denominators of the fractions.

    1/5 = 8/40
    1/8 = 5/40
    1/10 = 4/40

    The total for stocks is 17/40 of her portfolio.

    40/40 - 17/40 = 23/40

    To find the percentage, divide:

    23/40 = ??

    Then change that decimal to a percent.

  2. first find the common denominator. which is 40 so the fractions become 8/40 5/40 4/40. add them up and u get 17/40. then subtract 17/40 from 40/40 and you get 23/40 and that's your fraction. then divide 23 by 40 and you get 57.5% and that's your percent.
