5.5 is what percent of 256 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 256 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 256, so we can write it down as 100%=256.
4. We know, that x% equals 5.5 of the output value, so we can write it down as x%=5.5.
5. Now we have two simple equations:
1) 100%=256
2) x%=5.5
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=256/5.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5.5 is what percent of 256

100%/x%=256/5.5
(100/x)*x=(256/5.5)*x       - we multiply both sides of the equation by x
100=46.545454545455*x       - we divide both sides of the equation by (46.545454545455) to get x
100/46.545454545455=x
2.1484375=x
x=2.1484375

now we have:
5.5 is 2.1484375% of 256
