228.2 is what percent of 250 - 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 250 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 250, so we can write it down as 100%=250.
4. We know, that x% equals 228.2 of the output value, so we can write it down as x%=228.2.
5. Now we have two simple equations:
1) 100%=250
2) x%=228.2
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%=250/228.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 228.2 is what percent of 250

100%/x%=250/228.2
(100/x)*x=(250/228.2)*x       - we multiply both sides of the equation by x
100=1.0955302366345*x       - we divide both sides of the equation by (1.0955302366345) to get x
100/1.0955302366345=x
91.28=x
x=91.28

now we have:
228.2 is 91.28% of 250
