13 is what percent of 57086 - 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 57086 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 57086, so we can write it down as 100%=57086.
4. We know, that x% equals 13 of the output value, so we can write it down as x%=13.
5. Now we have two simple equations:
1) 100%=57086
2) x%=13
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%=57086/13
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13 is what percent of 57086

100%/x%=57086/13
(100/x)*x=(57086/13)*x       - we multiply both sides of the equation by x
100=4391.2307692308*x       - we divide both sides of the equation by (4391.2307692308) to get x
100/4391.2307692308=x
0.022772658795502=x
x=0.022772658795502

now we have:
13 is 0.022772658795502% of 57086
