627.04 is what percent of 810 - 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 810 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 810, so we can write it down as 100%=810.
4. We know, that x% equals 627.04 of the output value, so we can write it down as x%=627.04.
5. Now we have two simple equations:
1) 100%=810
2) x%=627.04
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%=810/627.04
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 627.04 is what percent of 810

100%/x%=810/627.04
(100/x)*x=(810/627.04)*x       - we multiply both sides of the equation by x
100=1.29178361827*x       - we divide both sides of the equation by (1.29178361827) to get x
100/1.29178361827=x
77.412345679012=x
x=77.412345679012

now we have:
627.04 is 77.412345679012% of 810
