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.
