321.62 is what percent of 3959.35 - 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 3959.35 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 3959.35, so we can write it down as 100%=3959.35.
4. We know, that x% equals 321.62 of the output value, so we can write it down as x%=321.62.
5. Now we have two simple equations:
1) 100%=3959.35
2) x%=321.62
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%=3959.35/321.62
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 321.62 is what percent of 3959.35

100%/x%=3959.35/321.62
(100/x)*x=(3959.35/321.62)*x       - we multiply both sides of the equation by x
100=12.310646104098*x       - we divide both sides of the equation by (12.310646104098) to get x
100/12.310646104098=x
8.1230505007135=x
x=8.1230505007135

now we have:
321.62 is 8.1230505007135% of 3959.35
