16.8 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 16.8 of the output value, so we can write it down as x%=16.8.
5. Now we have two simple equations:
1) 100%=130
2) x%=16.8
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%=130/16.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 16.8 is what percent of 130

100%/x%=130/16.8
(100/x)*x=(130/16.8)*x       - we multiply both sides of the equation by x
100=7.7380952380952*x       - we divide both sides of the equation by (7.7380952380952) to get x
100/7.7380952380952=x
12.923076923077=x
x=12.923076923077

now we have:
16.8 is 12.923076923077% of 130
