12 is 30 percent of what number?

To find out what number 12 is 30 percent of, we can use the formula for calculating percentages:

Formula: Part = (Percent / 100) × Whole

In this case, we know the part (12) and the percent (30), and we need to find the whole. Let’s rearrange the formula to solve for the whole:

Rearranged Formula: Whole = Part / (Percent / 100)

Now, plug in the known values:

Whole = 12 / (30 / 100)

Whole = 12 / 0.30

Whole = 40

So, 12 is 30 percent of 40.
