To determine what number 18 represents 50% of, you can set up the equation where you need to find a number x such that 50% of x equals 18.

This can be expressed mathematically as:

0.5 * x = 18

To find x, you can isolate it by dividing both sides by 0.5:

x = 18 / 0.5

Calculating that gives:

x = 36

Therefore, 18 is indeed 50% of 36. This means that when you take half of 36, you end up with 18, confirming that the correct answer is 36.
