6 is what percent of 389.9 - 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 389.9 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 389.9, so we can write it down as 100%=389.9.
4. We know, that x% equals 6 of the output value, so we can write it down as x%=6.
5. Now we have two simple equations:
1) 100%=389.9
2) x%=6
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%=389.9/6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6 is what percent of 389.9

100%/x%=389.9/6
(100/x)*x=(389.9/6)*x       - we multiply both sides of the equation by x
100=64.983333333333*x       - we divide both sides of the equation by (64.983333333333) to get x
100/64.983333333333=x
1.5388561169531=x
x=1.5388561169531

now we have:
6 is 1.5388561169531% of 389.9
