13 is what percent of 9600 - 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 9600 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 9600, so we can write it down as 100%=9600.
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%=9600
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%=9600/13
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 9600

100%/x%=9600/13
(100/x)*x=(9600/13)*x       - we multiply both sides of the equation by x
100=738.46153846154*x       - we divide both sides of the equation by (738.46153846154) to get x
100/738.46153846154=x
0.13541666666667=x
x=0.13541666666667

now we have:
13 is 0.13541666666667% of 9600
