    2. 224 is 25% of what number?

    We're looking for a much larger number. Think: one dollar is 25% of 4 dollars

    0.25w = 224

    w = 224/0.25

    w = 896

  • Math for Ms. Sue Or Steve -

    Oh.....

  • Math for Ms. Sue Or Steve -

    224 is 25% of what number

    you are told that 224 is 1/4 of a number. The number must be 4 times as big as 224.

    56 is 1/4 of 224
    224 is 1/4 of 896

    algebraically,

    224 = .25 x
    224/.25 = x
    x = 896

    it always helps to write down each step, then check your answer.

    you answered the question
    "25% of 224 is what?"
    not "225 is 25% of what?"
