728.91 is what percent of 818.5 - 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 818.5 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 818.5, so we can write it down as 100%=818.5.
4. We know, that x% equals 728.91 of the output value, so we can write it down as x%=728.91.
5. Now we have two simple equations:
1) 100%=818.5
2) x%=728.91
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%=818.5/728.91
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 728.91 is what percent of 818.5

100%/x%=818.5/728.91
(100/x)*x=(818.5/728.91)*x       - we multiply both sides of the equation by x
100=1.1229095498758*x       - we divide both sides of the equation by (1.1229095498758) to get x
100/1.1229095498758=x
89.054367745877=x
x=89.054367745877

now we have:
728.91 is 89.054367745877% of 818.5
