What is 0.255 percent of 3.51 - 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 3.51 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 3.51 is 100%, so we can write it down as 3.51=100%.
4. We know, that x is 0.255% of the output value, so we can write it down as x=0.255%.
5. Now we have two simple equations:
1) 3.51=100%
2) x=0.255%
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:
3.51/x=100%/0.255%
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 0.255% of 3.51

3.51/x=100/0.255
(3.51/x)*x=(100/0.255)*x       - we multiply both sides of the equation by x
3.51=392.1568627451*x       - we divide both sides of the equation by (392.1568627451) to get x
3.51/392.1568627451=x
0.0089505=x
x=0.0089505

now we have:
0.255% of 3.51=0.0089505
