12.22 is what percent of 21.11 - 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 21.11 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 21.11, so we can write it down as 100%=21.11.
4. We know, that x% equals 12.22 of the output value, so we can write it down as x%=12.22.
5. Now we have two simple equations:
1) 100%=21.11
2) x%=12.22
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%=21.11/12.22
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.22 is what percent of 21.11

100%/x%=21.11/12.22
(100/x)*x=(21.11/12.22)*x       - we multiply both sides of the equation by x
100=1.727495908347*x       - we divide both sides of the equation by (1.727495908347) to get x
100/1.727495908347=x
57.887257224064=x
x=57.887257224064

now we have:
12.22 is 57.887257224064% of 21.11
