58 is what percent of 1815 - 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 1815 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 1815, so we can write it down as 100%=1815.
4. We know, that x% equals 58 of the output value, so we can write it down as x%=58.
5. Now we have two simple equations:
1) 100%=1815
2) x%=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%=1815/58
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 58 is what percent of 1815

100%/x%=1815/58
(100/x)*x=(1815/58)*x       - we multiply both sides of the equation by x
100=31.293103448276*x       - we divide both sides of the equation by (31.293103448276) to get x
100/31.293103448276=x
3.1955922865014=x
x=3.1955922865014

now we have:
58 is 3.1955922865014% of 1815
