66.22 is what percent of 516 - 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 516 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 516, so we can write it down as 100%=516.
4. We know, that x% equals 66.22 of the output value, so we can write it down as x%=66.22.
5. Now we have two simple equations:
1) 100%=516
2) x%=66.22
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%=516/66.22
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 66.22 is what percent of 516

100%/x%=516/66.22
(100/x)*x=(516/66.22)*x       - we multiply both sides of the equation by x
100=7.7922077922078*x       - we divide both sides of the equation by (7.7922077922078) to get x
100/7.7922077922078=x
12.833333333333=x
x=12.833333333333

now we have:
66.22 is 12.833333333333% of 516
