222.8 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 222.8 of the output value, so we can write it down as x%=222.8.
5. Now we have two simple equations:
1) 100%=455
2) x%=222.8
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%=455/222.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 222.8 is what percent of 455

100%/x%=455/222.8
(100/x)*x=(455/222.8)*x       - we multiply both sides of the equation by x
100=2.0421903052065*x       - we divide both sides of the equation by (2.0421903052065) to get x
100/2.0421903052065=x
48.967032967033=x
x=48.967032967033

now we have:
222.8 is 48.967032967033% of 455
