515.85 is what percent of 2975 - 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 2975 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 2975, so we can write it down as 100%=2975.
4. We know, that x% equals 515.85 of the output value, so we can write it down as x%=515.85.
5. Now we have two simple equations:
1) 100%=2975
2) x%=515.85
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%=2975/515.85
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 515.85 is what percent of 2975

100%/x%=2975/515.85
(100/x)*x=(2975/515.85)*x       - we multiply both sides of the equation by x
100=5.767180381894*x       - we divide both sides of the equation by (5.767180381894) to get x
100/5.767180381894=x
17.339495798319=x
x=17.339495798319

now we have:
515.85 is 17.339495798319% of 2975
