19.97 is what percent of 130.36 - 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 130.36 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 130.36, so we can write it down as 100%=130.36.
4. We know, that x% equals 19.97 of the output value, so we can write it down as x%=19.97.
5. Now we have two simple equations:
1) 100%=130.36
2) x%=19.97
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%=130.36/19.97
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.97 is what percent of 130.36

100%/x%=130.36/19.97
(100/x)*x=(130.36/19.97)*x       - we multiply both sides of the equation by x
100=6.5277916875313*x       - we divide both sides of the equation by (6.5277916875313) to get x
100/6.5277916875313=x
15.319116293342=x
x=15.319116293342

now we have:
19.97 is 15.319116293342% of 130.36
