58 is what percent of 1686 - 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 1686 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 1686, so we can write it down as 100%=1686.
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%=1686
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%=1686/58
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 1686

100%/x%=1686/58
(100/x)*x=(1686/58)*x       - we multiply both sides of the equation by x
100=29.068965517241*x       - we divide both sides of the equation by (29.068965517241) to get x
100/29.068965517241=x
3.4400948991696=x
x=3.4400948991696

now we have:
58 is 3.4400948991696% of 1686
