455.25 is what percent of 555 - 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 555 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 555, so we can write it down as 100%=555.
4. We know, that x% equals 455.25 of the output value, so we can write it down as x%=455.25.
5. Now we have two simple equations:
1) 100%=555
2) x%=455.25
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%=555/455.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 455.25 is what percent of 555

100%/x%=555/455.25
(100/x)*x=(555/455.25)*x       - we multiply both sides of the equation by x
100=1.2191103789127*x       - we divide both sides of the equation by (1.2191103789127) to get x
100/1.2191103789127=x
82.027027027027=x
x=82.027027027027

now we have:
455.25 is 82.027027027027% of 555
