55 is 50% of what number

To find what number 55 is 50% of, you can set up a proportion using the following equation:

55 / x = 50 / 100

This equation represents the idea that "55 is to x as 50 is to 100," which is another way of saying "55 is 50% of x."

Now, we can solve for x by cross multiplying:

55 * 100 = 50 * x

5500 = 50x

To isolate x, divide both sides of the equation by 50:

x = 5500 / 50

x = 110

Therefore, 55 is 50% of 110.
