What is 6.39 percent of 388.91 - 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 388.91 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 388.91 is 100%, so we can write it down as 388.91=100%.
4. We know, that x is 6.39% of the output value, so we can write it down as x=6.39%.
5. Now we have two simple equations:
1) 388.91=100%
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:
388.91/x=100%/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 what is 6.39% of 388.91

388.91/x=100/6.39
(388.91/x)*x=(100/6.39)*x       - we multiply both sides of the equation by x
388.91=15.649452269171*x       - we divide both sides of the equation by (15.649452269171) to get x
388.91/15.649452269171=x
24.851349=x
x=24.851349

now we have:
6.39% of 388.91=24.851349
