21 is (66 and 2/3)% of what number?


I believe the answer is 14.
is it right?

  • Math -

    No. 14 is 66 2/3 of 21

    0.666667x = 21

    Your answer will be more than 21.

    this is confusing :(

    this is how I am solving.
    66 2/3 12
    ------- = -----
    100 W

    so i mulitiplyed 100x12= 2100.
    and from here I don't know how to insert 66 2/3 into calculator.

    2100 divided by 66.667?

    the choice to answers are
    14, 3.17, 315 and 31.5

    I know for sure that 14 is not the answer. i get different answers everything i play with that 2/3. please help

  • Math -

    66 2/3% = 200/300 = 2/3

    so just like Ms Sue stated ...

    (2/3)x = 21
    times 3
    2x = 63
    divide by 2
    x = 31.5


    Where did you get the 12 from in your solution?
    (dyslexia) ??

    had your ratio been:

    (66 2/3) / 100 = 21/w

    it would have worked:

    (200/3) / 100 = 21/w
    (200/3)w = 100(21)
    (200/3)w = 2100
    times 3
    200w = 6300
    w = 6300/200 = 31.5

  • Math -

    0.666667x = 21

    x = 21/0.666667

    x = 31.5
