To find the number, we start by setting up an equation. Let’s denote the unknown number as x.
According to the problem, 30% of this number equals 120. We can represent this mathematically as:
0.30 * x = 120
To isolate x, we need to divide both sides of the equation by 0.30:
x = 120 / 0.30
Now, performing the division, we get:
x = 400
Thus, the number we are looking for is 400. This means when you take 30% of 400, you indeed get 120.
