What is 8.5 percent of 255 - 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 255 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 255 is 100%, so we can write it down as 255=100%.
4. We know, that x is 8.5% of the output value, so we can write it down as x=8.5%.
5. Now we have two simple equations:
1) 255=100%
2) x=8.5%
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:
255/x=100%/8.5%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 8.5% of 255

255/x=100/8.5
(255/x)*x=(100/8.5)*x       - we multiply both sides of the equation by x
255=11.764705882353*x       - we divide both sides of the equation by (11.764705882353) to get x
255/11.764705882353=x
21.675=x
x=21.675

now we have:
8.5% of 255=21.675
