58.1 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 58.1 of the output value, so we can write it down as x%=58.1.
5. Now we have two simple equations:
1) 100%=129
2) x%=58.1
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%=129/58.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 58.1 is what percent of 129

100%/x%=129/58.1
(100/x)*x=(129/58.1)*x       - we multiply both sides of the equation by x
100=2.2203098106713*x       - we divide both sides of the equation by (2.2203098106713) to get x
100/2.2203098106713=x
45.038759689922=x
x=45.038759689922

now we have:
58.1 is 45.038759689922% of 129
