13 is what percent of 5286 - 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 5286 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 5286, so we can write it down as 100%=5286.
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%=5286
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%=5286/13
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 5286

100%/x%=5286/13
(100/x)*x=(5286/13)*x       - we multiply both sides of the equation by x
100=406.61538461538*x       - we divide both sides of the equation by (406.61538461538) to get x
100/406.61538461538=x
0.24593265228907=x
x=0.24593265228907

now we have:
13 is 0.24593265228907% of 5286
