Another way of saying this is "12 is 30% of what number." Knowing that "of" is code word for "multiply" and 30%= 0.30, we can set up this equation, where x = the unknown number:
To solve for x, all we have to do is divide both sides by 0.30, like so!
The answer is x = 40, or 30 percent of 40 is 12.
Hope this helps!
