165.5 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 165.5 of the output value, so we can write it down as x%=165.5.
5. Now we have two simple equations:
1) 100%=256
2) x%=165.5
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%=256/165.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 165.5 is what percent of 256

100%/x%=256/165.5
(100/x)*x=(256/165.5)*x       - we multiply both sides of the equation by x
100=1.5468277945619*x       - we divide both sides of the equation by (1.5468277945619) to get x
100/1.5468277945619=x
64.6484375=x
x=64.6484375

now we have:
165.5 is 64.6484375% of 256
