13 is what percent of 5700 - 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 5700 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 5700, so we can write it down as 100%=5700.
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%=5700
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%=5700/13
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 5700

100%/x%=5700/13
(100/x)*x=(5700/13)*x       - we multiply both sides of the equation by x
100=438.46153846154*x       - we divide both sides of the equation by (438.46153846154) to get x
100/438.46153846154=x
0.2280701754386=x
x=0.2280701754386

now we have:
13 is 0.2280701754386% of 5700
