13.25 is what percent of 72 - 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 72 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 72, so we can write it down as 100%=72.
4. We know, that x% equals 13.25 of the output value, so we can write it down as x%=13.25.
5. Now we have two simple equations:
1) 100%=72
2) x%=13.25
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%=72/13.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.25 is what percent of 72

100%/x%=72/13.25
(100/x)*x=(72/13.25)*x       - we multiply both sides of the equation by x
100=5.4339622641509*x       - we divide both sides of the equation by (5.4339622641509) to get x
100/5.4339622641509=x
18.402777777778=x
x=18.402777777778

now we have:
13.25 is 18.402777777778% of 72
