What is 0.42 percent of 39.884 - 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 39.884 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 39.884 is 100%, so we can write it down as 39.884=100%.
4. We know, that x is 0.42% of the output value, so we can write it down as x=0.42%.
5. Now we have two simple equations:
1) 39.884=100%
2) x=0.42%
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:
39.884/x=100%/0.42%
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 0.42% of 39.884

39.884/x=100/0.42
(39.884/x)*x=(100/0.42)*x       - we multiply both sides of the equation by x
39.884=238.09523809524*x       - we divide both sides of the equation by (238.09523809524) to get x
39.884/238.09523809524=x
0.1675128=x
x=0.1675128

now we have:
