What is 90.12 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 90.12% of the output value, so we can write it down as x=90.12%.
5. Now we have two simple equations:
1) 231=100%
2) x=90.12%
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%/90.12%
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 90.12% of 231

231/x=100/90.12
(231/x)*x=(100/90.12)*x       - we multiply both sides of the equation by x
231=1.109631602308*x       - we divide both sides of the equation by (1.109631602308) to get x
231/1.109631602308=x
208.1772=x
x=208.1772

now we have:
90.12% of 231=208.1772
