13 is what percent of 14400 - 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 14400 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 14400, so we can write it down as 100%=14400.
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%=14400
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%=14400/13
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 14400

100%/x%=14400/13
(100/x)*x=(14400/13)*x       - we multiply both sides of the equation by x
100=1107.6923076923*x       - we divide both sides of the equation by (1107.6923076923) to get x
100/1107.6923076923=x
0.090277777777778=x
x=0.090277777777778

now we have:
13 is 0.090277777777778% of 14400
