12.1 is what percent of 8.25 - 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 8.25 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 8.25, so we can write it down as 100%=8.25.
4. We know, that x% equals 12.1 of the output value, so we can write it down as x%=12.1.
5. Now we have two simple equations:
1) 100%=8.25
2) x%=12.1
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%=8.25/12.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.1 is what percent of 8.25

100%/x%=8.25/12.1
(100/x)*x=(8.25/12.1)*x       - we multiply both sides of the equation by x
100=0.68181818181818*x       - we divide both sides of the equation by (0.68181818181818) to get x
100/0.68181818181818=x
146.66666666667=x
x=146.66666666667

now we have:
12.1 is 146.66666666667% of 8.25
