What is 13.1 percent of 357 - 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 357 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 357 is 100%, so we can write it down as 357=100%.
4. We know, that x is 13.1% of the output value, so we can write it down as x=13.1%.
5. Now we have two simple equations:
1) 357=100%
2) x=13.1%
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:
357/x=100%/13.1%
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 13.1% of 357

357/x=100/13.1
(357/x)*x=(100/13.1)*x       - we multiply both sides of the equation by x
357=7.6335877862595*x       - we divide both sides of the equation by (7.6335877862595) to get x
357/7.6335877862595=x
46.767=x
x=46.767

now we have:
13.1% of 357=46.767
