122.2 is what percent of 286 - 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 286 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 286, so we can write it down as 100%=286.
4. We know, that x% equals 122.2 of the output value, so we can write it down as x%=122.2.
5. Now we have two simple equations:
1) 100%=286
2) x%=122.2
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%=286/122.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 122.2 is what percent of 286

100%/x%=286/122.2
(100/x)*x=(286/122.2)*x       - we multiply both sides of the equation by x
100=2.3404255319149*x       - we divide both sides of the equation by (2.3404255319149) to get x
100/2.3404255319149=x
42.727272727273=x
x=42.727272727273

now we have:
122.2 is 42.727272727273% of 286
