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 x.

Thus, .11% of x is 3.3

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

.0011 of x is 3.3

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

Using a similar "translation" for our problem,

.0011*x = 3.3

Divide both sides by .0011

x = 3.3/.0011 = 3000
