92.1 is what percent of 228 - 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 228 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 228, so we can write it down as 100%=228.
4. We know, that x% equals 92.1 of the output value, so we can write it down as x%=92.1.
5. Now we have two simple equations:
1) 100%=228
2) x%=92.1
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%=228/92.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 92.1 is what percent of 228

100%/x%=228/92.1
(100/x)*x=(228/92.1)*x       - we multiply both sides of the equation by x
100=2.4755700325733*x       - we divide both sides of the equation by (2.4755700325733) to get x
100/2.4755700325733=x
40.394736842105=x
x=40.394736842105

now we have:
92.1 is 40.394736842105% of 228
