57.1 is what percent of 357.1 - 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 357.1 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 100% equals 357.1, so we can write it down as 100%=357.1.
4. We know, that x% equals 57.1 of the output value, so we can write it down as x%=57.1.
5. Now we have two simple equations:
1) 100%=357.1
2) x%=57.1
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:
100%/x%=357.1/57.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 57.1 is what percent of 357.1

100%/x%=357.1/57.1
(100/x)*x=(357.1/57.1)*x       - we multiply both sides of the equation by x
100=6.2539404553415*x       - we divide both sides of the equation by (6.2539404553415) to get x
100/6.2539404553415=x
15.989918790255=x
x=15.989918790255

now we have:
57.1 is 15.989918790255% of 357.1
