What is 57.692307692308 percent of 390 - 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 390 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 390 is 100%, so we can write it down as 390=100%.
4. We know, that x is 57.692307692308% of the output value, so we can write it down as x=57.692307692308%.
5. Now we have two simple equations:
1) 390=100%
2) x=57.692307692308%
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:
390/x=100%/57.692307692308%
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 57.692307692308% of 390

390/x=100/57.692307692308
(390/x)*x=(100/57.692307692308)*x       - we multiply both sides of the equation by x
390=1.7333333333333*x       - we divide both sides of the equation by (1.7333333333333) to get x
390/1.7333333333333=x
225=x
x=225

now we have:
57.692307692308% of 390=225
