50.4 is what percent of 58 - 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 58 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 58, so we can write it down as 100%=58.
4. We know, that x% equals 50.4 of the output value, so we can write it down as x%=50.4.
5. Now we have two simple equations:
1) 100%=58
2) x%=50.4
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%=58/50.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 50.4 is what percent of 58

100%/x%=58/50.4
(100/x)*x=(58/50.4)*x       - we multiply both sides of the equation by x
100=1.1507936507937*x       - we divide both sides of the equation by (1.1507936507937) to get x
100/1.1507936507937=x
86.896551724138=x
x=86.896551724138

now we have:
50.4 is 86.896551724138% of 58
