What is 10.2 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 10.2% of the output value, so we can write it down as x=10.2%.
5. Now we have two simple equations:
1) 255=100%
2) x=10.2%
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%/10.2%
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 10.2% of 255

255/x=100/10.2
(255/x)*x=(100/10.2)*x       - we multiply both sides of the equation by x
255=9.8039215686275*x       - we divide both sides of the equation by (9.8039215686275) to get x
255/9.8039215686275=x
26.01=x
x=26.01

now we have:
10.2% of 255=26.01
