3000

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 $.0011$

$x = 3.3/.0011 = 3000$
