20.12 is what percent of 223 - 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 223 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 223, so we can write it down as 100%=223.
4. We know, that x% equals 20.12 of the output value, so we can write it down as x%=20.12.
5. Now we have two simple equations:
1) 100%=223
2) x%=20.12
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%=223/20.12
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20.12 is what percent of 223

100%/x%=223/20.12
(100/x)*x=(223/20.12)*x       - we multiply both sides of the equation by x
100=11.083499005964*x       - we divide both sides of the equation by (11.083499005964) to get x
100/11.083499005964=x
9.0224215246637=x
x=9.0224215246637

now we have:
20.12 is 9.0224215246637% of 223
