287.1 is what percent of 455 - 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 455 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 455, so we can write it down as 100%=455.
4. We know, that x% equals 287.1 of the output value, so we can write it down as x%=287.1.
5. Now we have two simple equations:
1) 100%=455
2) x%=287.1
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%=455/287.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 287.1 is what percent of 455

100%/x%=455/287.1
(100/x)*x=(455/287.1)*x       - we multiply both sides of the equation by x
100=1.5848136537792*x       - we divide both sides of the equation by (1.5848136537792) to get x
100/1.5848136537792=x
63.098901098901=x
x=63.098901098901

now we have:
287.1 is 63.098901098901% of 455
