What is 31.89 percent of 392 - 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 392 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 392 is 100%, so we can write it down as 392=100%.
4. We know, that x is 31.89% of the output value, so we can write it down as x=31.89%.
5. Now we have two simple equations:
1) 392=100%
2) x=31.89%
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:
392/x=100%/31.89%
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 31.89% of 392

392/x=100/31.89
(392/x)*x=(100/31.89)*x       - we multiply both sides of the equation by x
392=3.1357792411414*x       - we divide both sides of the equation by (3.1357792411414) to get x
392/3.1357792411414=x
125.0088=x
x=125.0088

now we have:
31.89% of 392=125.0088
