580.44 is what percent of 800 - 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 800 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 800, so we can write it down as 100%=800.
4. We know, that x% equals 580.44 of the output value, so we can write it down as x%=580.44.
5. Now we have two simple equations:
1) 100%=800
2) x%=580.44
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%=800/580.44
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 580.44 is what percent of 800

100%/x%=800/580.44
(100/x)*x=(800/580.44)*x       - we multiply both sides of the equation by x
100=1.3782647646613*x       - we divide both sides of the equation by (1.3782647646613) to get x
100/1.3782647646613=x
72.555=x
x=72.555

now we have:
580.44 is 72.555% of 800
