23.1 is what percent of 12.1 - 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 12.1 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 12.1, so we can write it down as 100%=12.1.
4. We know, that x% equals 23.1 of the output value, so we can write it down as x%=23.1.
5. Now we have two simple equations:
1) 100%=12.1
2) x%=23.1
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%=12.1/23.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 23.1 is what percent of 12.1

100%/x%=12.1/23.1
(100/x)*x=(12.1/23.1)*x       - we multiply both sides of the equation by x
100=0.52380952380952*x       - we divide both sides of the equation by (0.52380952380952) to get x
100/0.52380952380952=x
190.90909090909=x
x=190.90909090909

now we have:
23.1 is 190.90909090909% of 12.1
