12.92 is what percent of 72.81 - 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 72.81 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 72.81, so we can write it down as 100%=72.81.
4. We know, that x% equals 12.92 of the output value, so we can write it down as x%=12.92.
5. Now we have two simple equations:
1) 100%=72.81
2) x%=12.92
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%=72.81/12.92
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.92 is what percent of 72.81

100%/x%=72.81/12.92
(100/x)*x=(72.81/12.92)*x       - we multiply both sides of the equation by x
100=5.63544891641*x       - we divide both sides of the equation by (5.63544891641) to get x
100/5.63544891641=x
17.7448152726=x
x=17.7448152726

now we have:
12.92 is 17.7448152726% of 72.81
