515.75 is what percent of 610 - 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 610 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 610, so we can write it down as 100%=610.
4. We know, that x% equals 515.75 of the output value, so we can write it down as x%=515.75.
5. Now we have two simple equations:
1) 100%=610
2) x%=515.75
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%=610/515.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 515.75 is what percent of 610

100%/x%=610/515.75
(100/x)*x=(610/515.75)*x       - we multiply both sides of the equation by x
100=1.1827435773146*x       - we divide both sides of the equation by (1.1827435773146) to get x
100/1.1827435773146=x
84.549180327869=x
x=84.549180327869

now we have:
515.75 is 84.549180327869% of 610
