66.12 is what percent of 486.39 - 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 486.39 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 486.39, so we can write it down as 100%=486.39.
4. We know, that x% equals 66.12 of the output value, so we can write it down as x%=66.12.
5. Now we have two simple equations:
1) 100%=486.39
2) x%=66.12
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%=486.39/66.12
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 66.12 is what percent of 486.39

100%/x%=486.39/66.12
(100/x)*x=(486.39/66.12)*x       - we multiply both sides of the equation by x
100=7.3561705989111*x       - we divide both sides of the equation by (7.3561705989111) to get x
100/7.3561705989111=x
13.594029482514=x
x=13.594029482514

now we have:
