What is 0.055 percent of 231 - 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 231 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 231 is 100%, so we can write it down as 231=100%.
4. We know, that x is 0.055% of the output value, so we can write it down as x=0.055%.
5. Now we have two simple equations:
1) 231=100%
2) x=0.055%
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:
231/x=100%/0.055%
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 0.055% of 231

231/x=100/0.055
(231/x)*x=(100/0.055)*x       - we multiply both sides of the equation by x
231=1818.1818181818*x       - we divide both sides of the equation by (1818.1818181818) to get x
231/1818.1818181818=x
0.12705=x
x=0.12705

now we have:
0.055% of 231=0.12705
