180.57 is what percent of 450 - 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 450 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 450, so we can write it down as 100%=450.
4. We know, that x% equals 180.57 of the output value, so we can write it down as x%=180.57.
5. Now we have two simple equations:
1) 100%=450
2) x%=180.57
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%=450/180.57
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 180.57 is what percent of 450

100%/x%=450/180.57
(100/x)*x=(450/180.57)*x       - we multiply both sides of the equation by x
100=2.4921083236418*x       - we divide both sides of the equation by (2.4921083236418) to get x
100/2.4921083236418=x
40.126666666667=x
x=40.126666666667

now we have:
180.57 is 40.126666666667% of 450
