6.39 is what percent of 827 - 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 827 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 827, so we can write it down as 100%=827.
4. We know, that x% equals 6.39 of the output value, so we can write it down as x%=6.39.
5. Now we have two simple equations:
1) 100%=827
2) x%=6.39
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%=827/6.39
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6.39 is what percent of 827

100%/x%=827/6.39
(100/x)*x=(827/6.39)*x       - we multiply both sides of the equation by x
100=129.42097026604*x       - we divide both sides of the equation by (129.42097026604) to get x
100/129.42097026604=x
0.7726723095526=x
x=0.7726723095526

now we have:
6.39 is 0.7726723095526% of 827
