8.63 is what percent of 129 - 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 129 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 129, so we can write it down as 100%=129.
4. We know, that x% equals 8.63 of the output value, so we can write it down as x%=8.63.
5. Now we have two simple equations:
1) 100%=129
2) x%=8.63
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%=129/8.63
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.63 is what percent of 129

100%/x%=129/8.63
(100/x)*x=(129/8.63)*x       - we multiply both sides of the equation by x
100=14.94785631518*x       - we divide both sides of the equation by (14.94785631518) to get x
100/14.94785631518=x
6.6899224806202=x
x=6.6899224806202

now we have:
8.63 is 6.6899224806202% of 129
