58 is what percent of 85 - 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 85 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 85, so we can write it down as 100%=85.
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%=85
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%=85/58
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 85

100%/x%=85/58
(100/x)*x=(85/58)*x       - we multiply both sides of the equation by x
100=1.4655172413793*x       - we divide both sides of the equation by (1.4655172413793) to get x
100/1.4655172413793=x
68.235294117647=x
x=68.235294117647

now we have:
58 is 68.235294117647% of 85
