17.87 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 17.87 of the output value, so we can write it down as x%=17.87.
5. Now we have two simple equations:
1) 100%=130
2) x%=17.87
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%=130/17.87
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.87 is what percent of 130

100%/x%=130/17.87
(100/x)*x=(130/17.87)*x       - we multiply both sides of the equation by x
100=7.2747621712367*x       - we divide both sides of the equation by (7.2747621712367) to get x
100/7.2747621712367=x
13.746153846154=x
x=13.746153846154

now we have:
17.87 is 13.746153846154% of 130
