12.66 is what percent of 3020 - 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 3020 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 3020, so we can write it down as 100%=3020.
4. We know, that x% equals 12.66 of the output value, so we can write it down as x%=12.66.
5. Now we have two simple equations:
1) 100%=3020
2) x%=12.66
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%=3020/12.66
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.66 is what percent of 3020

100%/x%=3020/12.66
(100/x)*x=(3020/12.66)*x       - we multiply both sides of the equation by x
100=238.54660347551*x       - we divide both sides of the equation by (238.54660347551) to get x
100/238.54660347551=x
0.41920529801325=x
x=0.41920529801325

now we have:
12.66 is 0.41920529801325% of 3020
