17.99 is what percent of 130 - 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 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, so we can write it down as 100%=130.
4. We know, that x% equals 17.99 of the output value, so we can write it down as x%=17.99.
5. Now we have two simple equations:
1) 100%=130
2) x%=17.99
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%=130/17.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.99 is what percent of 130

100%/x%=130/17.99
(100/x)*x=(130/17.99)*x       - we multiply both sides of the equation by x
100=7.2262367982212*x       - we divide both sides of the equation by (7.2262367982212) to get x
100/7.2262367982212=x
13.838461538462=x
x=13.838461538462

now we have:
17.99 is 13.838461538462% of 130
