129 is what percent of 1083.33 - 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 1083.33 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 1083.33, so we can write it down as 100%=1083.33.
4. We know, that x% equals 129 of the output value, so we can write it down as x%=129.
5. Now we have two simple equations:
1) 100%=1083.33
2) x%=129
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%=1083.33/129
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 129 is what percent of 1083.33

100%/x%=1083.33/129
(100/x)*x=(1083.33/129)*x       - we multiply both sides of the equation by x
100=8.3979069767442*x       - we divide both sides of the equation by (8.3979069767442) to get x
100/8.3979069767442=x
11.907728946858=x
x=11.907728946858

now we have:
