Division-equal sharing

    Suppose that 3.2 units of Awesome are used in 40% of a cake. How many units of Awesome are used in a whole?

    The answer is 3.2 ÷ 0.4 = 8

    What I need to know is how to DRAW the question as equal division and not repeated subtraction.

    I attached a pic of what I think it looks like. Tell me if I'm headed in the right direction.

    The answer is easy to get using a proportion:
    [tex]\frac{3.2}{.4} = \frac{x}{1}[/tex]
    ==> x = 8

    That apparently isn't what you want. One possible way to go is to realize that 1.6 units of awesome are used in 20% (or one-fifth) of a cake, so if you have 5 equal chunks of the cake, you'll have 5 X 1.6 = 8 units of Awesome.
