30.58 is what percent of 47 - 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 47 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 47, so we can write it down as 100%=47.
4. We know, that x% equals 30.58 of the output value, so we can write it down as x%=30.58.
5. Now we have two simple equations:
1) 100%=47
2) x%=30.58
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%=47/30.58
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 30.58 is what percent of 47

100%/x%=47/30.58
(100/x)*x=(47/30.58)*x       - we multiply both sides of the equation by x
100=1.5369522563767*x       - we divide both sides of the equation by (1.5369522563767) to get x
100/1.5369522563767=x
65.063829787234=x
x=65.063829787234

now we have:
30.58 is 65.063829787234% of 47
