360 is 20 percent (%) of what number?

Let's call our missing number x.
Expressing this in terms of an equation, we get 360 = 20% * x
Since a percentage is just the percent number divided by 100, we have:
 360  = 20x 100

Multiply both sides of the equation through by 100 and simplify:
 360 * 100  = 20 * 100x 100

36000  =  20x

Since we want to solve for our missing number x, divide each side of the equation by 20
 36000 20
 =
 20x 20

Cancel both 20 and simplify:
 36000 20
 =
 20x 20

 x  = 36000 20

Therefore, our missing number x = 1800
Now we know that 360 is 20 percent (%) of 1800.
