3000

Explanation:

We must first convert the statement from words to an equation, and then proceed to solve the equation.

We will call the "what number" we are seeking xx.

Thus, .11%.11% of xx is 3.33.3

Converting .11%.11% to a proportion by dividing by 100%, we get:

.0011.0011 of xx is 3.33.3

If we say, for example, one half of 4 is 2, then we are multiplying 1/2 * 4124 and equating it to 22.

Using a similar "translation" for our problem,

.0011*x = 3.3.0011x=3.3

Divide both sides by .0011.0011

x = 3.3/.0011 = 3000x=3.3.0011=3000
