579.1 is what percent of 57.91 - 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 57.91 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 57.91, so we can write it down as 100%=57.91.
4. We know, that x% equals 579.1 of the output value, so we can write it down as x%=579.1.
5. Now we have two simple equations:
1) 100%=57.91
2) x%=579.1
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%=57.91/579.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 579.1 is what percent of 57.91

100%/x%=57.91/579.1
(100/x)*x=(57.91/579.1)*x       - we multiply both sides of the equation by x
100=0.1*x       - we divide both sides of the equation by (0.1) to get x
100/0.1=x
1000=x
x=1000

now we have:
579.1 is 1000% of 57.91
